- * @description
- *
- * This object provides a utility for producing rich Error messages within
- * Angular. It can be called as follows:
- *
- * var exampleMinErr = minErr('example');
- * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
- *
- * The above creates an instance of minErr in the example namespace. The
- * resulting error will have a namespaced error code of example.one.  The
- * resulting error will replace {0} with the value of foo, and {1} with the
- * value of bar. The object is not restricted in the number of arguments it can
- * take.
- *
- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.
- *
- * Since data will be parsed statically during a build step, some restrictions
- * are applied with respect to how minErr instances are created and called.
- * Instances should have names of the form namespaceMinErr for a minErr created
- * using minErr('namespace') . Error codes, namespaces and template strings
- * should all be static strings, not variables or general expressions.
- *
- * @param {string} module The namespace to use for the new minErr instance.
- * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
- *   error from returned function, for cases when a particular type of error is useful.
- * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

- * @ngdoc directive
- * @name ngApp
- * @module ng
- *
- * @element ANY
- * @param {angular.Module} ngApp an optional application
- *   {@link angular.module module} name to load.
- * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
- *   created in "strict-di" mode. This means that the application will fail to invoke functions which
- *   do not use explicit function annotation (and are thus unsuitable for minification), as described
- *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
- *   tracking down the root of these bugs.
- *
- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `<body>` or `<html>` tags.
- *
- * Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- * found in the document will be used to define the root element to auto-bootstrap as an
- * application. To run multiple applications in an HTML document you must manually bootstrap them using
- * {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application.  This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped and
- * should contain the application code needed or have dependencies on other modules that will
- * contain the code. See {@link angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` element then the
- * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * `ngApp` is the easiest, and most common, way to bootstrap an application.
- *
- <example module="ngAppDemo">
-   <file name="index.html">
-   <div ng-controller="ngAppDemoController">
-     I can add: {{a}} + {{b}} =  {{ a+b }}
-   </div>

-     $scope.a = 1;
-     $scope.b = 2;
-   });
-   </file>
- </example>
- *
- * Using `ngStrictDi`, you would see something like this:
- *
- <example ng-app-included="true">
-   <file name="index.html">
-   <div ng-app="ngAppStrictDemo" ng-strict-di>
-       <div ng-controller="GoodController1">
-           I can add: {{a}} + {{b}} =  {{ a+b }}

-              instantiate, by using explicit annotation style (see

- * each of the subsequent scripts. This prevents strange results in applications, where otherwise
- * multiple instances of Angular try to work on the DOM.

-     *
-     * The `angular.module` is a global place for creating, registering and retrieving Angular
-     * modules.
-     * All modules (angular core or 3rd party) that should be available to an application must be
-     * registered using this mechanism.
-     *
-     * When passed two or more arguments, a new module is created.  If passed only one argument, an
-     * existing module (the name passed as the first argument to `module`) is retrieved.
-     *
-     *
-     * # Module
-     *
-     * A module is a collection of services, directives, controllers, filters, and configuration information.
-     * `angular.module` is used to configure the {@link auto.$injector $injector}.
-     *
-     * ```js
-     * // Create a new module
-     * var myModule = angular.module('myModule', []);
-     *
-     * // register a new service
-     * myModule.value('appName', 'MyCoolApp');
-     *
-     * // configure existing services inside initialization blocks.
-     * myModule.config(['$locationProvider', function($locationProvider) {
-     *   // Configure existing providers
-     *   $locationProvider.hashPrefix('!');
-     * }]);
-     * ```
-     *
-     * Then you can create an injector and load your modules like this:
-     *
-     * ```js
-     * var injector = angular.injector(['ng', 'myModule'])
-     * ```
-     *
-     * However it's more likely that you'll just use
-     * {@link ng.directive:ngApp ngApp} or
-     * {@link angular.bootstrap} to simplify this process for you.
-     *
-     * @param {!string} name The name of the module to create or retrieve.
-     * @param {!Array.<string>=} requires If specified then new module is being created. If
-     *        unspecified then the module is being retrieved for further configuration.
-     * @param {Function=} configFn Optional configuration function for the module. Same as
-     *        {@link angular.Module#config Module#config()}.
-     * @returns {module} new module with the {@link angular.Module} api.

- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite."
- *
- * <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows
- * Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most
- * commonly needed functionality with the goal of having a very small footprint.</div>
- *
- * To use jQuery, simply load it before `DOMContentLoaded` event fired.
- *
- * <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or
- * jqLite; they are never raw DOM references.</div>
- *
- * ## Angular's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/)
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/)
- * - [`attr()`](http://api.jquery.com/attr/)
- * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/)
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces or selectors
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
- * - [`removeClass()`](http://api.jquery.com/removeClass/)
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/)
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers.
- * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * Angular also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- *   retrieves controller associated with the `ngController` directive. If `name` is provided as
- *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
- *   `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its parent.
- * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
- *   element or its parent.
- * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
- *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
- *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
- *   parent element is reached.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
- * @returns {Object} jQuery object.

- *
-
- * @param {Array.<string|Function>} modules A list of module functions or their aliases. See

- * @returns {function()} Injector function. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit injection

- * ```
- *
- * Sometimes you want to get access to the injector of a currently running Angular app

- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
- * $(document.body).append($div);
- *

- * @description
- *
- * `$injector` is used to retrieve object instances as defined by

- *
- * The following always holds true:

- *
- * # Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};

- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ## Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. *NOTE:* This does not work with
- * minification, and obfuscation tools since these tools change the argument names.
- *
- * ## `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.

-/**
- * @ngdoc method
- * @name $injector#annotate
- *
- * @description
- * Returns an array of service names which the function is requesting for injection. This API is
- * used by the injector to determine which services need to be injected into the function when the
- * function is invoked. There are three ways in which the function can be annotated with the needed
- * dependencies.
- *
- * # Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the function. This is done
- * by converting the function into a string using `toString()` method and extracting the argument
- * names.
- * ```js
- *   // Given
- *   function MyController($scope, $route) {
- *     // ...
- *   }
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * # The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * # The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @returns {Array.<string>} The names of the services which the function requires.

- * @description
- *
- * The {@link auto.$provide $provide} service has a number of methods for registering components
- * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
- * {@link angular.Module}.
- *
- * An Angular **service** is a singleton object created by a **service factory**.  These **service
- * factories** are functions which, in turn, are created by a **service provider**.
- * The **service providers** are constructor functions. When instantiated they must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` **service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider.  The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.
- *
- * * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the
- *     {@link auto.$injector $injector}
- * * {@link auto.$provide#constant constant(obj)} - registers a value/object that can be accessed by
- *     providers and services.
- * * {@link auto.$provide#value value(obj)} - registers a value/object that can only be accessed by
- *     services, not providers.
- * * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`,
- *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
- *     given factory function.
- * * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class`
- *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
- *      a new object using the given constructor function.
- *
- * See the individual methods for more information and examples.

-/**
- * @ngdoc method

- * @description
- *
- * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
- * are constructor functions, whose instances are responsible for "providing" a factory for a
- * service.
- *
- * Service provider names start with the name of the service they provide followed by `Provider`.
- * For example, the {@link ng.$log $log} service has a provider called
- * {@link ng.$logProvider $logProvider}.
- *
- * Service provider objects can have additional methods which allow configuration of the provider
- * and its service. Importantly, you can configure what kind of service is created by the `$get`
- * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
- * method {@link ng.$logProvider#debugEnabled debugEnabled}
- * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
- * console or not.
- *
- * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
-                        'Provider'` key.
- * @param {(Object|function())} provider If the provider is:
- *
- *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
- *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
- *   - `Constructor`: a new instance of the provider will be created using
- *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
- *
- * @returns {Object} registered provider instance
-
- * @example

- * @param {string} name The name of the service to decorate.
- * @param {function()} decorator This function will be invoked when the service needs to be
- *    instantiated and should return the decorated service instance. The function is called using
- *    the {@link auto.$injector#invoke injector.invoke} method and is therefore fully injectable.
- *    Local injection arguments:
- *
- *    * `$delegate` - The original service instance, which can be monkey patched, configured,
- *      decorated or delegated to.
- *
- * @example
- * Here we decorate the {@link ng.$log $log} service to convert warnings to errors by intercepting
- * calls to {@link ng.$log#error $log.warn()}.
- * ```js
- *   $provide.decorator('$log', ['$delegate', function($delegate) {
- *     $delegate.warn = $delegate.error;
- *     return $delegate;
- *   }]);

- * **Note:** This document is an in-depth reference of all directive options.

- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a "Directive Definition Object" (see below) that defines the directive properties,
- * or just the `postLink` function (all other properties will have the default values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       priority: 0,
- *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       transclude: false,
- *       restrict: 'A',
- *       scope: false,
- *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       controllerAs: 'stringAlias',
- *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       compile: function compile(tElement, tAttrs, transclude) {
- *         return {
- *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // link: {
- *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // link: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- *
- *
- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true, the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recomended that this feature be used on directives
- * which are not strictly behavioural (such as {@link api/ng.directive:ngClick ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link api/ng.directive:ngInclude ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined).
- *
- * #### `scope`
- * **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the
- * same element request a new scope, only one new scope is created. The new scope rule does not
- * apply for the root of the template since the root of the template always gets a new scope.
- *
- * **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from
- * normal scope in that it does not prototypically inherit from the parent scope. This is useful
- * when creating reusable components, which should not accidentally read or modify data in the
- * parent scope.
- *
- * The 'isolate' scope takes an object hash which defines a set of local scope properties
- * derived from the parent scope. These local properties are useful for aliasing values for
- * templates. Locals definition is a hash of local scope property to its source:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified  then the
- *   attribute name is assumed to be the same as the local name.
- *   Given `<widget my-attr="hello {{name}}">` and widget definition
- *   of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
- *   the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
- *   `localName` property on the widget scope. The `name` is read from the parent scope (not
- *   component scope).
- *
- * * `=` or `=attr` - set up bi-directional binding between a local scope property and the
- *   parent scope property of name defined via the value of the `attr` attribute. If no `attr`
- *   name is specified then the attribute name is assumed to be the same as the local name.
- *   Given `<widget my-attr="parentModel">` and widget definition of
- *   `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
- *   in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent
- *   scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You
- *   can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional.
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the
- *   local name. Given `<widget my-attr="count = count + value">` and widget definition of
- *   `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to
- *   a function wrapper for the `count = count + value` expression. Often it's desirable to
- *   pass data from the isolated scope via an expression to the parent scope, this can be
- *   done by passing a map of local variable names and values into the expression wrapper fn.
- *   For example, if the expression is `increment(amount)` then we can specify the amount value
- *   by calling the `localFn` as `localFn({amount: 22})`.
- *
- *
- * #### `bindToController`
- * When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController` will
- * allow a component to have its properties bound to the controller, rather than to scope. When the controller
- * is instantiated, the initial values of the isolate scope bindings are already available.
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and it is shared with other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement)`.
- *    * `scope`: optional argument to override the scope.
- *    * `cloneLinkingFn`: optional argument to create clones of the original transcluded content.
- *    * `futureParentElement`:
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkinFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the
- * injected argument will be an array in corresponding order. If no such directive can be
- * found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Controller alias at the directive scope. An alias for the controller so it
- * can be referenced at the directive template. The directive needs to define a scope for this
- * configuration to be used. Useful in the case when directive is used as component.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * api/ng.$sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#creating-custom-directives_creating-directives_template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * compile the content of the element and make it available to the directive.
- * Typically used with {@link ng.directive:ngTransclude
- * ngTransclude}. The advantage of transclusion is that the linking function receives a
- * transclusion function which is pre-bound to the correct scope. In a typical setup the widget
- * creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
- * scope. This makes it possible for the widget to have private state, and the transclusion to
- * be bound to the parent (pre-`isolate`) scope.
- *
- * * `true` - transclude the content of the directive.
- * * `'element'` - transclude the whole element including any directives defined at lower priority.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and a
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-error">
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - a controller instance - A controller instance if at least one directive on the
- *     element defines a controller. The controller is shared among all the directives, which allows
- *     the directives to use the controllers as a communication channel.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude`
- *     parameter of directive controllers, see there for details.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- * <a name="Attributes"></a>
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * accessing *Normalized attribute names:*
- * Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'.
- * the attributes object allows for normalized access to
- *   the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * Below is an example using `$compileProvider`.
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive
-        // factory function. The factory function injects the '$compile'
-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {
-            scope.$watch(
-              function(scope) {
-                 // watch the 'compile' expression for changes
-                return scope.$eval(attrs.compile);
-              },
-              function(value) {
-                // when the 'compile' expression changes
-                // assign it into the current DOM
-                element.html(value);
-
-                // compile the new DOM and link it to the current
-                // scope.
-                // NOTE: we only compile .childNodes so that
-                // we don't get into infinite loop compiling ourselves
-                $compile(element.contents())(scope);
-              }
-            );
-          };
-        });
-      })
-      .controller('GreeterController', ['$scope', function($scope) {
-        $scope.name = 'Angular';
-        $scope.html = 'Hello {{name}}';
-      }]);
-    </script>
-    <div ng-controller="GreeterController">
-      <input ng-model="name"> <br>
-      <textarea ng-model="html"></textarea> <br>

-       textarea.clear();
-       textarea.sendKeys('{{name}}!');

-     });
-   </file>
- </example>
-
- *
- *
- * @param {string|DOMElement} element Element or HTML string to compile into a template function.
- * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives.
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the
- *                 root element(s), not their children)
- * @returns {function(scope, cloneAttachFn=)} a link function which is used to bind template
- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: <br> `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *
- * For information on how the compiler works, see the
- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

-     * @description
-     * The `$http` service is a core Angular service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a configuration object —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}
-     * with two $http specific methods: `success` and `error`.
-     *
-     * ```js
-     *   $http({method: 'GET', url: '/someUrl'}).
-     *     success(function(data, status, headers, config) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }).
-     *     error(function(data, status, headers, config) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * Since the returned value of calling the $http function is a `promise`, you can also use
-     * the `then` method to register callbacks, and these callbacks will receive a single argument –
-     * an object representing the response. See the API signature and type info below for more
-     * details.
-     *
-     * A response status code between 200 and 299 is considered a success status and
-     * will result in the success callback being called. Note that if the response is a redirect,
-     * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
-     * called for such responses.
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests.
-     *
-     * ```js
-     *   $http.get('/someUrl').success(successCallback);
-     *   $http.post('/someUrl', data).success(successCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - {@link ng.$http#get $http.get}
-     * - {@link ng.$http#head $http.head}
-     * - {@link ng.$http#post $http.post}
-     * - {@link ng.$http#put $http.put}
-     * - {@link ng.$http#delete $http.delete}
-     * - {@link ng.$http#jsonp $http.jsonp}
-     * - {@link ng.$http#patch $http.patch}
-     *
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
-     *   - `Accept: application/json, text/plain, * / *`
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object passed when
-     * calling `$http(config)`, which overrides the defaults without changing them globally.
-     *
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`{function(data, headersGetter)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * To enable caching, set the request configuration `cache` property to `true` (to use default
-     * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
-     * When the cache is enabled, `$http` stores the response from the server in the specified
-     * cache. The next time the same request is made, the response is served from the cache without
-     * sending a request to the server.
-     *
-     * Note that even if the response is served from cache, delivery of the data is asynchronous in
-     * the same way that real requests are.
-     *
-     * If there are multiple GET requests for the same URL that should be cached using the same
-     * cache, but the cache is not populated yet, only one request to the server will be made and
-     * the remaining requests will be fulfilled using the response from the first request.
-     *
-     * You can change the default cache to a new object (built with
-     * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
-     * {@link ng.$http#properties_defaults `$http.defaults.cache`} property. All requests who set
-     * their `cache` property to `true` will now use this cache object.
-     *
-     * If you set the default cache to `false` then only requests that specify their own custom
-     * cache object will be cached.
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http `config` object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
-     * an unauthorized site can gain your user's private data. Angular provides a mechanism
-     * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
-     * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
-     * JavaScript that runs on your domain could read the cookie, your server can be assured that
-     * the XHR came from JavaScript running on your domain. The header will not be set for
-     * cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
-     * that only JavaScript running on your domain could have sent the request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
-     * or the per-request config object.
-     *
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be turned
-     *      to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be
-     *      JSONified.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent.
-     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
-     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
-     *    - **transformRequest** –
-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.
-     *      See {@link #overriding-the-default-transformations-per-request Overriding the Default Transformations}
-     *    - **transformResponse** –
-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      response body and headers and returns its transformed (typically deserialized) version.
-     *      See {@link #overriding-the-default-transformations-per-request Overriding the Default Transformations}
-     *    - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
-     *      GET request, otherwise if a cache instance built with
-     *      {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
-     *      caching.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.
-     *    - **responseType** - `{string}` - see
-     *      [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
-     *
-     * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
-     *   standard `then` method and two http specific methods: `success` and `error`. The `then`
-     *   method takes two arguments a success and an error callback which will be called with a
-     *   response object. The `success` and `error` methods take a single argument - a function that
-     *   will be called when the request succeeds or fails respectively. The arguments passed into
-     *   these functions are destructured representation of the response object passed into the
-     *   `then` method. The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with the transform
-     *     functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *
-     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
-     *   requests. This is primarily meant to be used for debugging purposes.

-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * ####Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example>
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.</p>
-     *    </div>
-     *  </file>
-     * </example>
-     *
-     * @param {string} text The text with markup to interpolate.
-     * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have
-     *    embedded expression in order to return an interpolation function. Strings with no
-     *    embedded expression will return null for the interpolation function.
-     * @param {string=} trustedContext when provided, the returned function passes the interpolated

-     *    trustedContext)} before returning it.  Refer to the {@link ng.$sce $sce} service that

-// Sandboxing Angular Expressions
-// ------------------------------
-// Angular expressions are generally considered safe because these expressions only have direct
-// access to $scope and locals. However, one can obtain the ability to execute arbitrary JS code by
-// obtaining a reference to native JS functions such as the Function constructor.
-//
-// As an example, consider the following Angular expression:
-//
-//   {}.toString.constructor('alert("evil JS code")')
-//
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
-// against the expression language, but not to prevent exploits that were enabled by exposing
-// sensitive JavaScript or browser apis on Scope. Exposing such objects on a Scope is never a good
-// practice and therefore we are not even trying to protect against interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular expression unless a
-// window or some DOM object that has a reference to window is published onto a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
-// native objects.

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- * return $q(function(resolve, reject) {
- *   // perform some asynchronous operation, resolve or reject the promise when appropriate.
- *   setInterval(function() {
- *     if (pollStatus > 0) {
- *       resolve(polledValue);
- *     } else if (pollStatus < 0) {
- *       reject(polledValue);
- *     } else {
- *       pollStatus = pollAgain(function(value) {
- *         polledValue = value;
- *       });
- *     }
- *   }, 10000);
- * }).
- *   then(function(value) {
- *     // handle success
- *   }, function(reason) {
- *     // handle failure
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q`, `scope` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the return value of the
- *   `successCallback`, `errorCallback`. It also notifies via the return value of the
- *   `notifyCallback` method. The promise cannot be resolved or rejected from the notifyCallback
- *   method.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback)` – allows you to observe either the fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release resources or do some
- *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- *   more information.
- *
- *   Because `finally` is a reserved word in JavaScript and reserved keywords are not supported as
- *   property names by ES3, you'll need to invoke the method like `promise['finally'](callback)` to
- *   make your code IE8 and Android 2.x compatible.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- *   mechanism in angular, which means faster propagation of resolution or rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- *  # Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);
- *    }));
- *  ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- *   rejecting the newly created promise. The first parameter is a function which resolves the
- *   promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- *   - No closures, instead use prototypical inheritance for API
- *   - Internal state needs to be stored on scope directly, which means that private state is
- *     exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- *   - this means that in order to keep the same order of execution as addition we have to add
- *     items to the array at the beginning (unshift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- *   - Using an array would be slow since inserts in middle are expensive so we use linked list
- *
- * There are few watches then a lot of observers. This is why you don't want the observer to be
- * implemented in the same way as watch. Watch requires return of initialization function which
- * are expensive to construct.

-       * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
-       *   $digest()} and should return the value that will be watched. (Since
-       *   {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the
-       *   `watchExpression` can execute multiple times per
-       *   {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
-       *   see below). Inequality is determined according to reference inequality,
-       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
-       *    via the `!==` Javascript operator, unless `objectEquality == true`
-       *   (see next point)
-       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
-       *   according to the {@link angular.equals} function. To save the value of the object for
-       *   later comparison, the {@link angular.copy} function is used. This therefore means that
-       *   watching complex objects will have adverse memory and performance implications.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
-       * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a
-       * change is detected, be prepared for multiple calls to your listener.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *

-       * ```js

-       * @ngdoc method
-       * @name $rootScope.Scope#$digest
-       * @kind function
-       *
-       * @description
-       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
-       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
-       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
-       * until no more listeners are firing. This means that it is possible to get into an infinite
-       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
-       * iterations exceeds 10.
-       *
-       * Usually, you don't call `$digest()` directly in
-       * {@link ng.directive:ngController controllers} or in
-       * {@link ng.$compileProvider#directive directives}.
-       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
-       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
-       *
-       * If you want to be notified whenever `$digest()` is called,
-       * you can register a `watchExpression` function with
-       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
-       *
-       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
-       *
-       * # Example
-       * ```js
-           var scope = ...;
-           scope.name = 'misko';
-           scope.counter = 0;
-
-           expect(scope.counter).toEqual(0);
-           scope.$watch('name', function(newValue, oldValue) {
-             scope.counter = scope.counter + 1;
-           });
-           expect(scope.counter).toEqual(0);
-
-           scope.$digest();

-           scope.$digest();
-           // but now it will not be called unless the value changes
-           expect(scope.counter).toEqual(1);
-
-           scope.name = 'adam';

-       * Because we are calling into the angular framework we need to perform proper scope life
-       * cycle of {@link ng.$exceptionHandler exception handling},
-       * {@link ng.$rootScope.Scope#$digest executing watches}.
-       *
-       * ## Life cycle
-       *
-       * # Pseudo-Code of `$apply()`
-       * ```js
-           function $apply(expr) {
-             try {
-               return $eval(expr);
-             } catch (e) {
-               $exceptionHandler(e);
-             } finally {
-               $root.$digest();
-             }
-           }
-       * ```
-       *
-       *
-       * Scope's `$apply()` method transitions through the following stages:
-       *
-       * 1. The {@link guide/expression expression} is executed using the
-       *    {@link ng.$rootScope.Scope#$eval $eval()} method.
-       * 2. Any exceptions from the execution of the expression are forwarded to the
-       *    {@link ng.$exceptionHandler $exceptionHandler} service.
-       * 3. The {@link ng.$rootScope.Scope#$watch watch} listeners are fired immediately after the
-       *    expression was executed using the {@link ng.$rootScope.Scope#$digest $digest()} method.
-       *
-       *
-       * @param {(string|function())=} exp An angular expression to be executed.
-       *
-       *    - `string`: execute using the rules as defined in {@link guide/expression expression}.
-       *    - `function(scope)`: execute the function with current `scope` parameter.
-       *
-       * @returns {*} The result of evaluating the expression.

- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict

- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
- * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
- * can override it completely to change the behavior of `$sce`, the common case would
- * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as

- *      'http://srv*.assets.example.com/**'

- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * # Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
- * contexts to result in a value that is marked as safe to use for that context.  One example of
- * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
- *
- * As of version 1.2, Angular ships with SCE enabled by default.
- *
- * Note:  When enabled (the default), IE8 in quirks mode is not supported.  In this mode, IE8 allows
- * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
- * to the top of your HTML document.
- *
- * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * <input ng-model="userHtml">
- * <div ng-bind-html="userHtml"></div>
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV.
- * In a more realistic example, one may be rendering user comments, blog articles, etc. via
- * bindings.  (HTML is just one example of a context where rendering user controlled input creates
- * security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
- * determine that something explicitly says it's safe to use a value for binding in that
- * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
- * for those values that you can easily tell are safe - because they were received from your server,
- * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
- * allowing only the files in a specific directory to do this.  Ensuring that the internal API
- * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * obtain values that will be accepted by SCE / privileged contexts.
- *
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
- * ng.$sce#parse $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
- * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol as the application
- * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
- * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded.  This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
- * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
- *
- * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
- * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document.  You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *
- * <a name="contexts"></a>
- * ## What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
- * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
- * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
- * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
- *
- * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'.  It's a useful wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
- *      not appropriate to use in for a scheme, domain, etc. as it would match too much.  (e.g.
- *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
- *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
- *      have good test coverage.).  For instance, the use of `.` in the regex is correct only in a
- *      small number of cases.  A `.` character in the regex used when matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to regular expressions
- *      if they as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
- *    - If you are generating your JavaScript from some other templating engine (not
- *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you might need more than
- *      one level of escaping depending on your templating engine and the way you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it might be good
- *      enough before coding your own.  e.g. Ruby has
- *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

- *     By default, HTML that isn't explicitly trusted (e.g. Alice's comment) is sanitized when

- * ## Can I disable SCE completely?
- *
- * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
- * for little coding overhead.  It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects.
- *   $sceProvider.enabled(false);
- * });
- * ```

-  /* Design notes on the default implementation for SCE.
-   *
-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
-   *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
-   *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  For values that were
-   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
-   *     such a value.
-   *
-   * - getTrusted(contextEnum, value)
-   *     This function should return the a value that is safe to use in the context specified by
-   *     contextEnum or throw and exception otherwise.
-   *
-   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
-   * return the same object passed in if it was found in the registry under a compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an exception for special
-   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
-   *
-   *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
-   * is purely an implementation details.
-   *
-   * The contract is simply this:
-   *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
-   *     will also succeed.
-   *
-   * Inheritance happens to capture this in a natural way.  In some future, we
-   * may not use inheritance anymore.  That is OK because no code outside of
-   * sce.js and sceSpecs.js would need to be aware of this detail.

-/**
- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL.  This approach has wide
- * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers.  However, the parsed components will not be set if the URL assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
- * properties such as protocol, hostname, port, etc.
- *
- * IE7 does not normalize the URL when assigned to an anchor node.  (Apparently, it does, if one
- * uses the inner HTML approach to assign the URL as part of an HTML snippet -
- * http://stackoverflow.com/a/472729)  However, setting img[src] does normalize the URL.
- * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
- * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
- * method and IE < 8 is unsupported.

- * Filters are just functions which transform input to an output. However filters need to be
- * Dependency Injected. To achieve this a filter definition consists of a factory function which is
- * annotated with dependencies and is responsible for creating a filter function.
- *
- * ```js
- *   // Filter registration
- *   function MyModule($provide, $filterProvider) {
- *     // create a service to demonstrate injection (not always needed)
- *     $provide.value('greet', function(name){

- *     // register a filter factory which uses the
- *     // greet service to demonstrate DI.
- *     $filterProvider.register('greet', function(greet){
- *       // return the filter function which uses the greet service
- *       // to generate salutation
- *       return function(text) {
- *         // filters need to be forgiving so check input validity
- *         return text && greet(text) || text;
- *       };
- *     });
- *   }
- * ```
- *
- * The filter function is registered with the `$injector` under the filter name suffix with
- * `Filter`.
- *
- * ```js
- *   it('should be the same instance', inject(
- *     function($filterProvider) {
- *       $filterProvider.register('reverse', function(){
- *         return ...;

-/**
- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is evaluated as an expression and the resulting value is used for substring match against
- *     the contents of the `array`. All strings or objects with string properties in `array` that contain this string
- *     will be returned. The predicate can be negated by prefixing the string with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- *     which have property `name` containing "M" and property `phone` containing "1". A special
- *     property name `$` can be used (as in `{$:"text"}`) to accept a match against any
- *     property of the object. That's equivalent to the simple substring match with a `string`
- *     as described above. The predicate can be negated by prefixing the string with `!`.
- *     For Example `{name: "!M"}` predicate will return an array of items which have property `name`
- *     not containing "M".
- *
- *   - `function(value, index)`: A predicate function can be used to write arbitrary filters. The
- *     function is called for each element of `array`. The final result is an array of those
- *     elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
- *     determining if the expected value (from the filter expression) and actual value (from
- *     the object in the array) should be considered a match.
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to compare and
- *     should return true if the item should be included in filtered result.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(expected, actual)}`.
- *     this is essentially strict comparison of expected and actual.
- *
- *   - `false|undefined`: A short hand for a function which will look for a substring match in case
- *     insensitive way.
- *

- * @ngdoc filter
- * @name date
- * @kind function
- *
- * @description
- *   Formats `date` to a string based on the requested `format`.
- *
- *   `format` string can be composed of the following elements:
- *
- *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- *   * `'MMMM'`: Month in year (January-December)
- *   * `'MMM'`: Month in year (Jan-Dec)
- *   * `'MM'`: Month in year, padded (01-12)
- *   * `'M'`: Month in year (1-12)
- *   * `'dd'`: Day in month, padded (01-31)
- *   * `'d'`: Day in month (1-31)
- *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
- *   * `'EEE'`: Day in Week, (Sun-Sat)
- *   * `'HH'`: Hour in day, padded (00-23)
- *   * `'H'`: Hour in day (0-23)
- *   * `'hh'`: Hour in AM/PM, padded (01-12)
- *   * `'h'`: Hour in AM/PM, (1-12)
- *   * `'mm'`: Minute in hour, padded (00-59)
- *   * `'m'`: Minute in hour (0-59)
- *   * `'ss'`: Second in minute, padded (00-59)
- *   * `'s'`: Second in minute (0-59)
- *   * `'.sss' or ',sss'`: Millisecond in second, padded (000-999)
- *   * `'a'`: AM/PM marker
- *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- *   * `'ww'`: ISO-8601 week of year (00-53)
- *   * `'w'`: ISO-8601 week of year (0-53)
- *
- *   `format` string can also be one of the following predefined
- *   {@link guide/i18n localizable formats}:
- *
- *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- *     (e.g. Sep 3, 2010 12:05:08 PM)
- *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
- *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
- *     (e.g. Friday, September 3, 2010)
- *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
- *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
- *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
- *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- *   (e.g. `"h 'o''clock'"`).
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- *    specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- *    `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. Right now, only `'UTC'` is supported.
- *    If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
- * for strings and numerically for numbers. Note: if you notice numbers are not being sorted
- * correctly, make sure they are actually being saved as numbers and not strings.
- *
- * @param {Array} array The array to sort.
- * @param {function(*)|string|Array.<(function(*)|string)>} expression A predicate to be
- *    used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `function`: Getter function. The result of this function will be sorted using the
- *      `<`, `=`, `>` operator.
- *    - `string`: An Angular expression. The result of this expression is used to compare elements
- *      (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
- *      3 first characters of a property called `name`). The result of a constant expression
- *      is interpreted as a property name to be used in comparisons (for example `"special name"`
- *      to sort object by the value of their `special name` property). An expression can be
- *      optionally prefixed with `+` or `-` to control ascending or descending sort order
- *      (for example, `+name` or `-name`).
- *    - `Array`: An array of function or string predicates. The first predicate in the array
- *      is used for sorting, but when two items are equivalent, the next predicate is used.
- *
- * @param {boolean=} reverse Reverse the order of the array.
- * @returns {Array} Sorted copy of the source array.

- /**
- * @ngdoc directive
- * @name form
- * @restrict E
- *
- * @description
- * Directive that instantiates
- * {@link form.FormController FormController}.
- *
- * If the `name` attribute is specified, the form controller is published onto the current scope under
- * this name.
- *
- * # Alias: {@link ng.directive:ngForm `ngForm`}
- *
- * In Angular forms can be nested. This means that the outer form is valid when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
- * Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to
- * `<form>` but can be nested.  This allows you to have nested forms, which is very useful when
- * using Angular validation directives in forms that are dynamically generated using the
- * {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name`
- * attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an
- * `ngForm` directive and nest these in an outer `form` element.
- *
- *
- * # CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- *
- * # Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side Angular applications is different than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
- * page reload that sends the data to the server. Instead some javascript logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, Angular prevents the default action (form submission to the server) unless the
- * `<form>` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method should be called when
- * a form is submitted:
- *
- * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
- * - {@link ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
- * or {@link ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML specification:
- *
- * - If a form has only one input field then hitting enter in this field triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ## Animation Hooks
- *
- * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm are similar to how
- * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
-    <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
-      <file name="index.html">
-       <script>
-         angular.module('formExample', [])

-        .my-form {
-          -webkit-transition:all linear 0.5s;
-          transition:all linear 0.5s;
-          background: transparent;
-        }
-        .my-form.ng-invalid {
-          background: red;
-        }
-       </style>
-       <form name="myForm" ng-controller="FormController" class="my-form">

-   * month format (yyyy-MM), for example: `2009-01`. The model must always be a Date object. In the event the model is
-   * not set to the first of the month, the first of that model's month is assumed.
-   *
-   * The timezone to be used to read/write the `Date` instance in the model can be defined using

-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be
-   * a valid ISO month format (yyyy-MM).
-   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must
-   * be a valid ISO month format (yyyy-MM).
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to

-       {@link ngModel.NgModelController#$setValidity $setValidity()},
-       and return `undefined` for invalid values.
-
- *
- * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
-       the model value changes. Each function is called, in turn, passing the value through to the
-       next. Used to format / convert values for display in the control and validation.
- * ```js
- * function formatter(value) {
- *   if (value) {
- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(formatter);
- * ```
- *
- * @property {Object.<string, function>} $validators A collection of validators that are applied
- *      whenever the model value changes. The key value within the object refers to the name of the
- *      validator while the function refers to the validation operation. The validation operation is
- *      provided with the model value as an argument and must return a true or false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&
- *          /[a-z]+/.test(value) &&
- *          /[A-Z]+/.test(value) &&
- *          /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- *      is expected to return a promise when it is run during the model validation process. Once the promise
- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. Also, keep in mind that all
- *      asynchronous validators will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).
- *      then(function resolved() {
- *        //username exists, this means validation fails
- *        return $q.reject('exists');
- *      }, function rejected() {
- *        //username does not exist, therefore this validation passes
- *        return true;
- *      });
- * };
- * ```
- *
- * @param {string} name The name of the validator.
- * @param {Function} validationFn The validation function that will be run.
- *
- * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
- *     view value has changed. It is called with no arguments, and its return value is ignored.
- *     This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the control yet.
- * @property {boolean} $dirty True if user has already interacted with the control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.

- * @description
- *
- * `NgModelController` provides API for the `ng-model` directive. The controller contains
- * services for data-binding, validation, CSS updates, and value formatting and parsing. It
- * purposefully does not contain any logic which deals with DOM rendering or listening to
- * DOM events. Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding.
- *
- * ## Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.  This will not work on older browsers.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;

-        min-height: 20px;
-      }

-   * @ngdoc method
-   * @name ngModel.NgModelController#$setViewValue
-   *
-   * @description
-   * Update the view value.
-   *
-   * This method should be called when an input directive want to change the view value; typically,
-   * this is done from within a DOM event handler.
-   *
-   * For example {@link ng.directive:input input} calls it when the value of the input changes and
-   * {@link ng.directive:select select} calls it when an option is selected.
-   *
-   * If the new `value` is an object (rather than a string or a number), we should make a copy of the
-   * object before passing it to `$setViewValue`.  This is because `ngModel` does not perform a deep
-   * watch of objects, it only looks for a change of identity. If you only change the property of
-   * the object then ngModel will not realise that the object has changed and will not invoke the
-   * `$parsers` and `$validators` pipelines.
-   *
-   * For this reason, you should not change properties of the copy once it has been passed to
-   * `$setViewValue`. Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * When this method is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute.
-   *
-   * Lastly, all the registered change listeners, in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   *
-   * Note that calling this function does not trigger a `$digest`.
-   *
-   * @param {string} value Value from the view.
-   * @param {string} trigger Event that triggered the update.

-/**
- * @ngdoc directive
- * @name ngModel
- *
- * @element input
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [https://github.com/angular/angular.js/wiki/Understanding-Scopes]
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[dateTimeLocal] dateTimeLocal}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid` is set if the model is valid.
- *  - `ng-invalid` is set if the model is invalid.
- *  - `ng-pristine` is set if the model is pristine.
- *  - `ng-dirty` is set if the model is dirty.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes are: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);
-       </script>
-       <style>
-         .my-input {
-           -webkit-transition:all linear 0.5s;
-           transition:all linear 0.5s;
-           background: transparent;
-         }
-         .my-input.ng-invalid {
-           color:white;
-           background: red;
-         }
-       </style>
-       Update input to see transitions when valid/invalid.
-       Integer is a valid value.
-       <form name="testForm" ng-controller="ExampleController">
-         <input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input" />
-       </form>
-     </file>
- * </example>
- *
- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different than what the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           Name:
-           <input type="text" name="userName"
-                  ng-model="user.name"
-                  ng-model-options="{ getterSetter: true }" />
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function (newName) {
-               if (angular.isDefined(newName)) {
-                 _name = newName;
-               }
-               return _name;
-             }
-           };
-         }]);

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- *   list item is respected. This implies that the user of the directive is responsible for
- *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- *   when joining the list items back together) and whitespace around each list item is stripped
- *   before it is added to the model.
- *
- * ### Example with Validation

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
- * events that will trigger a model update and/or a debouncing delay so that the actual update only
- * takes place when a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different than the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
- *   - `updateOn`: string specifying which event should be the input bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging of the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 500, 'blur': 0} }"`
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
-       `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date">`, `<input type="time">`, ... . Right now, the only supported value is `'UTC'`,
- *     otherwise the default timezone of the browser will be used.
- *
- * @example
-
-  The following example shows how to override immediate updates. Changes on the inputs within the
-  form will update the model only when the control loses focus (blur event). If `escape` key is
-  pressed while the input field is focused, the value is reset to the value in the current model.

- * @ngdoc directive
- * @name ngBind
- * @restrict AC
- *
- * @description
- * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element
- * with the value of a given expression, and to update the text content when the value of that
- * expression changes.
- *
- * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like
- * `{{ expression }}` which is similar but less verbose.
- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the page is loading.
- *
- * An alternative solution to this problem would be using the
- * {@link ng.directive:ngCloak ngCloak} directive.
- *
- *

- * @param {expression} ngBind {@link guide/expression Expression} to evaluate.

- * @ngdoc directive

- *
- * @description
- * Creates a binding that will innerHTML the result of evaluating the `expression` into the current
- * element in a secure way.  By default, the innerHTML-ed content will be sanitized using the {@link
- * ngSanitize.$sanitize $sanitize} service.  To utilize this functionality, ensure that `$sanitize`
- * is available, for example, by including {@link ngSanitize} in your module's dependencies (not in
- * core Angular.)  You may also bypass sanitization for values you know are safe. To do so, bind to
- * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example
- * under {@link ng.$sce#Example Strict Contextual Escaping (SCE)}.
- *
- * Note: If a `$sanitize` service is unavailable and the bound value isn't explicitly trusted, you
- * will have an exception (instead of an exploit.)

-/**
- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an array, each element of the array should be a string that is
- * one or more space-delimited class names.
- *
- * 3. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * The directive won't add duplicate classes if a particular class was already set.
- *
- * When the expression changes, the previously added classes are removed and only then the
- * new classes are added.
- *
- * @animations
- * add - happens just before the class is applied to the element
- * remove - happens just before the class is removed from the element
- *
- * @element ANY
- * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case of a map, the
- *   names of the properties whose values are truthy will be added as css classes to the
- *   element.
- *
- * @example Example that demonstrates basic bindings via ngClass directive.
-   <example>
-     <file name="index.html">
-       <p ng-class="{strike: deleted, bold: important, red: error}">Map Syntax Example</p>
-       <input type="checkbox" ng-model="deleted"> deleted (apply "strike" class)<br>
-       <input type="checkbox" ng-model="important"> important (apply "bold" class)<br>

-
-   ## Animations
-
-   The example below demonstrates how to perform animations using ngClass.
-
-   <example module="ngAnimate" deps="angular-animate.js" animations="true">
-     <file name="index.html">
-      <input id="setbtn" type="button" value="set" ng-click="myVar='my-class'">
-      <input id="clearbtn" type="button" value="clear" ng-click="myVar=''">
-      <br>
-      <span class="base-class" ng-class="myVar">Sample Text</span>
-     </file>
-     <file name="style.css">
-       .base-class {
-         -webkit-transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;
-       }
-     </file>
-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);
-
-         element(by.id('clearbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link ngAnimate.$animate#addclass $animate.addClass} and
-   {@link ngAnimate.$animate#removeclass $animate.removeClass}.

-/**
- * @ngdoc directive
- * @name ngCloak
- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.
- *
- * Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they
- * cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css
- * class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below.
- *
- * @element ANY
- *
- * @example
-   <example>
-     <file name="index.html">
-        <div id="template1" ng-cloak>{{ 'hello' }}</div>

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (not recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using `this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally used in boilerplates
- * and in this guide. However, there are advantages to binding properties directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.

- *   <file name="index.html">

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @element html
- * @description
- * Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support.
- *
- * This is necessary when developing things like Google Chrome Extensions.
- *
- * CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things).
- * For Angular to be CSP compatible there are only two things that we need to do differently:
- *
- * - don't use `Function` constructor to generate optimized value getters
- * - don't inject custom stylesheet into the document
- *
- * AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp`
- * directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will
- * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
- * be raised.
- *
- * CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically
- * includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}).
- * To make those directives work in CSP mode, include the `angular-csp.css` manually.
- *
- * Angular tries to autodetect if CSP is active and automatically turn on the CSP-safe mode. This
- * autodetection however triggers a CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on the root element of the application or on the `angular.js` script tag, whichever
- * appears first in the html document.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>
-   ```
- */
-
-// ngCsp is not implemented as a proper directive any more, because we need it be processed while we
-// bootstrap the system (before $parse is instantiated), for this reason we just have
-// the csp.isActive() fn that looks for ng-csp attribute anywhere in the current doc

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/The-Nuances-of-Scope-Prototypal-Inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * enter - happens just after the ngIf contents change and a new DOM element is created and injected into the ngIf container
- * leave - happens just before the ngIf contents are removed from the DOM
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
- *     element is added to the DOM tree.
- *
- * @example
-  <example module="ngAnimate" deps="angular-animate.js" animations="true">
-    <file name="index.html">
-      Click me: <input type="checkbox" ng-model="checked" ng-init="checked=true" /><br/>

- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy may further restrict whether the template is successfully loaded.
- * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
- * access on some browsers.
- *
- * @animations
- * enter - animation is used to bring new content into the browser.
- * leave - animation is used to animate existing content away.
- *
- * The enter and leave animation occur concurrently.

- *
- * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
- *                 make sure you wrap it in **single** quotes, e.g. `src="'myPartialTemplate.html'"`.
- * @param {string=} onload Expression to evaluate when a new partial is loaded.
- *
- * @param {string=} autoscroll Whether `ngInclude` should call {@link ng.$anchorScroll
- *                  $anchorScroll} to scroll the viewport after the content is loaded.
- *
- *                  - If the attribute is not set, disable scrolling.
- *                  - If the attribute is set without value, enable scrolling.

-/**
- * @ngdoc directive
- * @name ngPluralize
- * @restrict EA
- *
- * @description
- * `ngPluralize` is a directive that displays messages according to en-US localization rules.
- * These rules are bundled with angular.js, but can be overridden
- * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
- * by specifying the mappings between
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * and the strings to be displayed.
- *
- * # Plural categories and explicit number rules
- * There are two
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * in Angular's default en-US locale: "one" and "other".
- *
- * While a plural category may match many numbers (for example, in en-US locale, "other" can match
- * any number that is not 1), an explicit number rule can only match one number. For example, the
- * explicit number rule for "3" matches the number 3. There are examples of plural categories
- * and explicit number rules throughout the rest of this documentation.
- *
- * # Configuring ngPluralize
- * You configure ngPluralize by providing 2 attributes: `count` and `when`.
- * You can also provide an optional attribute, `offset`.
- *
- * The value of the `count` attribute can be either a string or an {@link guide/expression
- * Angular expression}; these are evaluated on the current scope for its bound value.
- *
- * The `when` attribute specifies the mappings between plural categories and the actual
- * string to be displayed. The value of the attribute should be a JSON object.
- *
- * The following example shows how to configure ngPluralize:
- *
- * ```html
- * <ng-pluralize count="personCount"
-                 when="{'0': 'Nobody is viewing.',
- *                      'one': '1 person is viewing.',
- *                      'other': '{} people are viewing.'}">
- * </ng-pluralize>
- *```
- *
- * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
- * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
- * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
- * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
- * show "a dozen people are viewing".
- *
- * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
- * into pluralized strings. In the previous example, Angular will replace `{}` with
- * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
- * for <span ng-non-bindable>{{numberExpression}}</span>.
- *
- * # Configuring ngPluralize with offset
- * The `offset` attribute allows further customization of pluralized text, which can result in
- * a better user experience. For example, instead of the message "4 people are viewing this document",
- * you might display "John, Kate and 2 others are viewing this document".
- * The offset attribute allows you to offset a number by any desired value.
- * Let's take a look at an example:
- *
- * ```html
- * <ng-pluralize count="personCount" offset=2
- *               when="{'0': 'Nobody is viewing.',
- *                      '1': '{{person1}} is viewing.',
- *                      '2': '{{person1}} and {{person2}} are viewing.',
- *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
- *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
- * </ng-pluralize>
- * ```
- *
- * Notice that we are still using two plural categories(one, other), but we added
- * three explicit number rules 0, 1 and 2.
- * When one person, perhaps John, views the document, "John is viewing" will be shown.
- * When three people view the document, no explicit number rule is found, so
- * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
- * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
- * is shown.
- *
- * Note that when you specify offsets, you must provide explicit number rules for
- * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
- * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
- * plural categories "one" and "other".
- *
- * @param {string|expression} count The variable to be bound to.
- * @param {string} when The mapping between plural category to its corresponding strings.
- * @param {number=} offset Offset to deduct from the total number.
- *
- * @example
-    <example module="pluralizeExample">
-      <file name="index.html">
-        <script>
-          angular.module('pluralizeExample', [])
-            .controller('ExampleController', ['$scope', function($scope) {

-              $scope.person2 = 'Misko';
-              $scope.personCount = 1;

-/**
- * @ngdoc directive
- * @name ngRepeat
- *
- * @description
- * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
- * instance gets its own scope, where the given loop variable is set to the current collection item,
- * and `$index` is set to the item index or key.
- *
- * Special properties are exposed on the local scope of each template instance, including:
- *
- * | Variable  | Type            | Details                                                                     |
- * |-----------|-----------------|-----------------------------------------------------------------------------|
- * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
- * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
- * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
- * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
- * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
- * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
- *
- * Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
- * This may be useful when, for instance, nesting ngRepeats.
- *
- * # Special repeat start and end points
- * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   <header ng-repeat-start="item in items">
- *     Header {{ item }}
- *   </header>
- *   <div class="body">
- *     Body {{ item }}
- *   </div>
- *   <footer ng-repeat-end>
- *     Footer {{ item }}
- *   </footer>
- * ```
- *
- * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
- * ```html
- *   <header>
- *     Header A
- *   </header>
- *   <div class="body">
- *     Body A
- *   </div>
- *   <footer>
- *     Footer A
- *   </footer>
- *   <header>
- *     Header B
- *   </header>
- *   <div class="body">
- *     Body B
- *   </div>
- *   <footer>
- *     Footer B
- *   </footer>
- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * **.enter** - when a new item is added to the list or when an item is revealed after a filter
- *
- * **.leave** - when an item is removed from the list or when an item is filtered out
- *
- * **.move** - when an adjacent item is filtered out causing a reorder or when the item contents are reordered
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
- *     and `expression` is the scope expression giving the collection to enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking function
- *     which can be used to associate the objects in the collection with the DOM elements. If no tracking function
- *     is specified the ng-repeat associates elements by identity in the collection. It is an error to have
- *     more than one tracking function to resolve to the same key. (This would mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)  Filters should be applied to the expression,
- *     before specifying a tracking expression.
- *
- *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
- *     will be associated by item identity in the array.
- *
- *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is empty.
- *
- *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
- *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
- *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
- *     element in the same way in the DOM.
- *
- *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
- *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
- *     property is same.
- *
- *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
- *     to items in conjunction with a tracking expression.
- *
- * @example
- * This example initializes the scope to a list of names and
- * then uses `ngRepeat` to display every person:
-  <example module="ngAnimate" deps="angular-animate.js" animations="true">
-    <file name="index.html">

-/**
- * @ngdoc directive
- * @name ngShow
- *
- * @description
- * The `ngShow` directive shows or hides the given HTML element based on the expression
- * provided to the ngShow attribute. The element is shown or hidden by removing or adding
- * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is visible) -->
- * <div ng-show="myValue"></div>
- *
- * <!-- when $scope.myValue is falsy (element is hidden) -->
- * <div ng-show="myValue" class="ng-hide"></div>
- * ```
- *
- * When the ngShow expression evaluates to a falsy value then the ng-hide CSS class is added to the class
- * attribute on the element causing it to become hidden. When truthy, the ng-hide CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as simple
- * as changing the display style on a HTML list item would make hidden elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
- *
- * ### Overriding .ng-hide
- *
- * By default, the `.ng-hide` class will style the element with `display:none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
- * class in CSS:
- *
- * ```css
- * .ng-hide {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display:block!important;
- *   position:absolute;
- *   top:-9999px;
- *   left:-9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the display style.
- *
- * ## A note about animations with ngShow
- *
- * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
- * is true and false. This system works like the animation system present with ngClass except that
- * you must also include the !important flag to override the display property
- * so that you can perform an animation when the element is hidden during the time of the animation.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   /&#42; this is required as of 1.3x to properly
- *      apply all styling in a show/hide animation &#42;/
- *   transition:0s linear all;
- * }
- *
- * .my-element.ng-hide-add-active,
- * .my-element.ng-hide-remove-active {
- *   /&#42; the transition is defined in the active class &#42;/
- *   transition:1s linear all;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3.0-beta.11, there is no need to change the display
- * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
- *
- * @animations
- * addClass: .ng-hide - happens after the ngShow expression evaluates to a truthy value and the just before contents are set to visible
- * removeClass: .ng-hide - happens after the ngShow expression evaluates to a non truthy value and just before the contents are set to hidden
- *
- * @element ANY
- * @param {expression} ngShow If the {@link guide/expression expression} is truthy
- *     then the element is shown or hidden respectively.

-/**
- * @ngdoc directive
- * @name ngHide
- *
- * @description
- * The `ngHide` directive shows or hides the given HTML element based on the expression
- * provided to the ngHide attribute. The element is shown or hidden by removing or adding
- * the `ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is hidden) -->
- * <div ng-hide="myValue" class="ng-hide"></div>
- *
- * <!-- when $scope.myValue is falsy (element is visible) -->
- * <div ng-hide="myValue"></div>
- * ```
- *
- * When the ngHide expression evaluates to a truthy value then the .ng-hide CSS class is added to the class
- * attribute on the element causing it to become hidden. When falsy, the ng-hide CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the .ng-hide CSS class. This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as simple
- * as changing the display style on a HTML list item would make hidden elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
- *
- * ### Overriding .ng-hide
- *
- * By default, the `.ng-hide` class will style the element with `display:none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
- * class in CSS:
- *
- * ```css
- * .ng-hide {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display:block!important;
- *   position:absolute;
- *   top:-9999px;
- *   left:-9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the display style.
- *
- * ## A note about animations with ngHide
- *
- * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
- * is true and false. This system works like the animation system present with ngClass, except that the `.ng-hide`
- * CSS class is added and removed for you instead of your own CSS class.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   transition:0.5s linear all;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3.0-beta.11, there is no need to change the display
- * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
- *
- * @animations
- * removeClass: .ng-hide - happens after the ngHide expression evaluates to a truthy value and just before the contents are set to hidden
- * addClass: .ng-hide - happens after the ngHide expression evaluates to a non truthy value and just before the contents are set to visible
- *
- * @element ANY
- * @param {expression} ngHide If the {@link guide/expression expression} is truthy then
- *     the element is shown or hidden respectively.

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, you define a container element
- * (where you place the directive), place an expression on the **`on="..."` attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
- * attribute is displayed.
- *
- * <div class="alert alert-info">
- * Be aware that the attribute values to match against cannot be expressions. They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
- * value of the expression `$scope.someVal`.
- * </div>
-
- * @animations
- * enter - happens after the ngSwitch contents change and the matched child element is placed inside the container
- * leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM
- *
- * @usage
- *
- * ```
- * <ANY ng-switch="expression">
- *   <ANY ng-switch-when="matchValue1">...</ANY>
- *   <ANY ng-switch-when="matchValue2">...</ANY>
- *   <ANY ng-switch-default>...</ANY>
- * </ANY>
- * ```
- *
- *
- * @scope
- * @priority 1200
- * @param {*} ngSwitch|on expression to match against <tt>ng-switch-when</tt>.
- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.

- * @ngdoc directive
- * @name select
- * @restrict E
- *
- * @description
- * HTML `SELECT` element with angular data-binding.
- *
- * # `ngOptions`
- *
- * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
- * elements for the `<select>` element using the array or object obtained by evaluating the
- * `ngOptions` comprehension_expression.
- *
- * When an item in the `<select>` menu is selected, the array element or object property
- * represented by the selected option will be bound to the model identified by the `ngModel`
- * directive.
- *
- * <div class="alert alert-warning">
- * **Note:** `ngModel` compares by reference, not value. This is important when binding to an
- * array of objects. See an example [in this jsfiddle](http://jsfiddle.net/qWzTb/).
- * </div>
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
- * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
- * option. See example below for demonstration.
- *
- * <div class="alert alert-warning">
- * **Note:** `ngOptions` provides an iterator facility for the `<option>` element which should be used instead
- * of {@link ng.directive:ngRepeat ngRepeat} when you want the
- * `select` model to be bound to a non-string value. This is because an option element can only
- * be bound to string values at present.
- * </div>
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required The control is considered valid only if value is entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {comprehension_expression=} ngOptions in one of the following forms:
- *
- *   * for array data sources:
- *     * `label` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
- *     * `label`  **`group by`** `group` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *   * for object data sources:
- *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`group by`** `group`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *
- * Where:
- *
- *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
- *   * `value`: local variable which will refer to each item in the `array` or each property value
- *      of `object` during iteration.
- *   * `key`: local variable which will refer to a property name in `object` during iteration.
- *   * `label`: The result of this expression will be the label for `<option>` element. The
- *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
- *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
- *      element. If not specified, `select` expression will default to `value`.
- *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
- *      DOM element.
- *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
- *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
- *     `value` variable (e.g. `value.propertyName`).
