- * @ngdoc module
- * @name ngAnimate
- * @description
- *
- * The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives.
- *
- * <div doc-module-components="ngAnimate"></div>
- *
- * # Usage
- *
- * To see animations in action, all that is required is to define the appropriate CSS classes
- * or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are:
- * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation
- * by using the `$animate` service.
- *
- * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:
- *
- * | Directive                                                                                                 | Supported Animations                                                     |
- * |-----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
- * | {@link ng.directive:ngRepeat#usage_animations ngRepeat}                                                   | enter, leave and move                                                    |
- * | {@link ngRoute.directive:ngView#usage_animations ngView}                                                  | enter and leave                                                          |
- * | {@link ng.directive:ngInclude#usage_animations ngInclude}                                                 | enter and leave                                                          |
- * | {@link ng.directive:ngSwitch#usage_animations ngSwitch}                                                   | enter and leave                                                          |
- * | {@link ng.directive:ngIf#usage_animations ngIf}                                                           | enter and leave                                                          |
- * | {@link ng.directive:ngClass#usage_animations ngClass}                                                     | add and remove (the CSS class(es) present)                               |
- * | {@link ng.directive:ngShow#usage_animations ngShow} & {@link ng.directive:ngHide#usage_animations ngHide} | add and remove (the ng-hide class value)                                 |
- * | {@link ng.directive:form#usage_animations form} & {@link ng.directive:ngModel#usage_animations ngModel}   | add and remove (dirty, pristine, valid, invalid & all other validations) |
- * | {@link ngMessages.directive:ngMessage#usage_animations ngMessages}                                        | add and remove (ng-active & ng-inactive)                                 |
- * | {@link ngMessages.directive:ngMessage#usage_animations ngMessage}                                         | enter and leave                                                          |
- *
- * You can find out more information about animations upon visiting each directive page.
- *
- * Below is an example of how to apply animations to a directive that supports animation hooks:
- *
- * ```html
- * <style type="text/css">
- * .slide.ng-enter, .slide.ng-leave {
- *   -webkit-transition:0.5s linear all;
- *   transition:0.5s linear all;
- * }
- *
- * .slide.ng-enter { }        /&#42; starting animations for enter &#42;/
- * .slide.ng-enter.ng-enter-active { } /&#42; terminal animations for enter &#42;/
- * .slide.ng-leave { }        /&#42; starting animations for leave &#42;/
- * .slide.ng-leave.ng-leave-active { } /&#42; terminal animations for leave &#42;/
- * </style>
- *
- * <!--
- * the animate service will automatically add .ng-enter and .ng-leave to the element
- * to trigger the CSS transition/animations
- * -->
- * <ANY class="slide" ng-include="..."></ANY>
- * ```
- *
- * Keep in mind that, by default, if an animation is running, any child elements cannot be animated
- * until the parent element's animation has completed. This blocking feature can be overridden by
- * placing the `ng-animate-children` attribute on a parent container tag.
- *
- * ```html
- * <div class="slide-animation" ng-if="on" ng-animate-children>
- *   <div class="fade-animation" ng-if="on">
- *     <div class="explode-animation" ng-if="on">
- *        ...
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * When the `on` expression value changes and an animation is triggered then each of the elements within
- * will all animate without the block being applied to child elements.
- *
- * ## Are animations run when the application starts?
- * No they are not. When an application is bootstrapped Angular will disable animations from running to avoid
- * a frenzy of animations from being triggered as soon as the browser has rendered the screen. For this to work,
- * Angular will wait for two digest cycles until enabling animations. From there on, any animation-triggering
- * layout changes in the application will trigger animations as normal.
- *
- * In addition, upon bootstrap, if the routing system or any directives or load remote data (via $http) then Angular
- * will automatically extend the wait time to enable animations once **all** of the outbound HTTP requests
- * are complete.
- *
- * <h2>CSS-defined Animations</h2>
- * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
- * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
- * and can be used to play along with this naming structure.
- *
- * The following code below demonstrates how to perform animations using **CSS transitions** with Angular:
- *
- * ```html
- * <style type="text/css">
- * /&#42;
- *  The animate class is apart of the element and the ng-enter class
- *  is attached to the element once the enter animation event is triggered
- * &#42;/
- * .reveal-animation.ng-enter {
- *  -webkit-transition: 1s linear all; /&#42; Safari/Chrome &#42;/
- *  transition: 1s linear all; /&#42; All other modern browsers and IE10+ &#42;/
- *
- *  /&#42; The animation preparation code &#42;/
- *  opacity: 0;
- * }
- *
- * /&#42;
- *  Keep in mind that you want to combine both CSS
- *  classes together to avoid any CSS-specificity
- *  conflicts
- * &#42;/
- * .reveal-animation.ng-enter.ng-enter-active {
- *  /&#42; The animation code itself &#42;/
- *  opacity: 1;
- * }
- * </style>
- *
- * <div class="view-container">
- *   <div ng-view class="reveal-animation"></div>
- * </div>
- * ```
- *
- * The following code below demonstrates how to perform animations using **CSS animations** with Angular:
- *
- * ```html
- * <style type="text/css">
- * .reveal-animation.ng-enter {
- *   -webkit-animation: enter_sequence 1s linear; /&#42; Safari/Chrome &#42;/
- *   animation: enter_sequence 1s linear; /&#42; IE10+ and Future Browsers &#42;/
- * }
- * @-webkit-keyframes enter_sequence {
- *   from { opacity:0; }
- *   to { opacity:1; }
- * }
- * @keyframes enter_sequence {
- *   from { opacity:0; }
- *   to { opacity:1; }
- * }
- * </style>
- *
- * <div class="view-container">
- *   <div ng-view class="reveal-animation"></div>
- * </div>
- * ```
- *
- * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.
- *
- * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add
- * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically
- * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
- * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
- * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
- * has no CSS transition/animation classes applied to it.
- *
- * ### Structural transition animations
- *
- * Structural transitions (such as enter, leave and move) will always apply a `0s none` transition
- * value to force the browser into rendering the styles defined in the setup (.ng-enter, .ng-leave
- * or .ng-move) class. This means that any active transition animations operating on the element
- * will be cut off to make way for the enter, leave or move animation.
- *
- * ### Class-based transition animations
- *
- * Class-based transitions refer to transition animations that are triggered when a CSS class is
- * added to or removed from the element (via `$animate.addClass`, `$animate.removeClass`,
- * `$animate.setClass`, or by directives such as `ngClass`, `ngModel` and `form`).
- * They are different when compared to structural animations since they **do not cancel existing
- * animations** nor do they **block successive transitions** from rendering on the same element.
- * This distinction allows for **multiple class-based transitions** to be performed on the same element.
- *
- * In addition to ngAnimate supporting the default (natural) functionality of class-based transition
- * animations, ngAnimate also decorates the element with starting and ending CSS classes to aid the
- * developer in further styling the element throughout the transition animation. Earlier versions
- * of ngAnimate may have caused natural CSS transitions to break and not render properly due to
- * $animate temporarily blocking transitions using `0s none` in order to allow the setup CSS class
- * (the `-add` or `-remove` class) to be applied without triggering an animation. However, as of
- * **version 1.3**, this workaround has been removed with ngAnimate and all non-ngAnimate CSS
- * class transitions are compatible with ngAnimate.
- *
- * There is, however, one special case when dealing with class-based transitions in ngAnimate.
- * When rendering class-based transitions that make use of the setup and active CSS classes
- * (e.g. `.fade-add` and `.fade-add-active` for when `.fade` is added) be sure to define
- * the transition value **on the active CSS class** and not the setup class.
- *
- * ```css
- * .fade-add {
- *   /&#42; remember to place a 0s transition here
- *      to ensure that the styles are applied instantly
- *      even if the element already has a transition style &#42;/
- *   transition:0s linear all;
- *
- *   /&#42; starting CSS styles &#42;/
- *   opacity:1;
- * }
- * .fade-add.fade-add-active {
- *   /&#42; this will be the length of the animation &#42;/
- *   transition:1s linear all;
- *   opacity:0;
- * }
- * ```
- *
- * The setup CSS class (in this case `.fade-add`) also has a transition style property, however, it
- * has a duration of zero. This may not be required, however, incase the browser is unable to render
- * the styling present in this CSS class instantly then it could be that the browser is attempting
- * to perform an unnecessary transition.
- *
- * This workaround, however, does not apply to  standard class-based transitions that are rendered
- * when a CSS class containing a transition is applied to an element:
- *
- * ```css
- * .fade {
- *   /&#42; this works as expected &#42;/
- *   transition:1s linear all;
- *   opacity:0;
- * }
- * ```
- *
- * Please keep this in mind when coding the CSS markup that will be used within class-based transitions.
- * Also, try not to mix the two class-based animation flavors together since the CSS code may become
- * overly complex.
- *
- * ### CSS Staggering Animations
- * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
- * curtain-like effect. The ngAnimate module, as of 1.2.0, supports staggering animations and the stagger effect can be
- * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
- * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
- * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
- *
- * ```css
- * .my-animation.ng-enter {
- *   /&#42; standard transition code &#42;/
- *   -webkit-transition: 1s linear all;
- *   transition: 1s linear all;
- *   opacity:0;
- * }
- * .my-animation.ng-enter-stagger {
- *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
- *   -webkit-transition-delay: 0.1s;
- *   transition-delay: 0.1s;
- *
- *   /&#42; in case the stagger doesn't work then these two values
- *    must be set to 0 to avoid an accidental CSS inheritance &#42;/
- *   -webkit-transition-duration: 0s;
- *   transition-duration: 0s;
- * }
- * .my-animation.ng-enter.ng-enter-active {
- *   /&#42; standard transition styles &#42;/
- *   opacity:1;
- * }
- * ```
- *
- * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
- * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
- * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
- * will also be reset if more than 10ms has passed after the last animation has been fired.
- *
- * The following code will issue the **ng-leave-stagger** event on the element provided:
- *
- * ```js
- * var kids = parent.children();
- *
- * $animate.leave(kids[0]); //stagger index=0
- * $animate.leave(kids[1]); //stagger index=1
- * $animate.leave(kids[2]); //stagger index=2
- * $animate.leave(kids[3]); //stagger index=3
- * $animate.leave(kids[4]); //stagger index=4
- *
- * $timeout(function() {
- *   //stagger has reset itself
- *   $animate.leave(kids[5]); //stagger index=0
- *   $animate.leave(kids[6]); //stagger index=1
- * }, 100, false);
- * ```
- *
- * Stagger animations are currently only supported within CSS-defined animations.
- *
- * ## JavaScript-defined Animations
- * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
- * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.
- *
- * ```js
- * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application.
- * var ngModule = angular.module('YourApp', ['ngAnimate']);
- * ngModule.animation('.my-crazy-animation', function() {
- *   return {
- *     enter: function(element, done) {
- *       //run the animation here and call done when the animation is complete
- *       return function(cancelled) {
- *         //this (optional) function will be called when the animation
- *         //completes or when the animation is cancelled (the cancelled
- *         //flag will be set to true if cancelled).
- *       };
- *     },
- *     leave: function(element, done) { },
- *     move: function(element, done) { },
- *
- *     //animation that can be triggered before the class is added
- *     beforeAddClass: function(element, className, done) { },
- *
- *     //animation that can be triggered after the class is added
- *     addClass: function(element, className, done) { },
- *
- *     //animation that can be triggered before the class is removed
- *     beforeRemoveClass: function(element, className, done) { },
- *
- *     //animation that can be triggered after the class is removed
- *     removeClass: function(element, className, done) { }
- *   };
- * });
- * ```
- *
- * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
- * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
- * the element's CSS class attribute value and then run the matching animation event function (if found).
- * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will
- * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported).
- *
- * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
- * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
- * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
- * or transition code that is defined via a stylesheet).

-      /**
-       * @ngdoc service
-       * @name $animate
-       * @kind object
-       *
-       * @description
-       * The `$animate` service provides animation detection support while performing DOM operations (enter, leave and move) as well as during addClass and removeClass operations.
-       * When any of these operations are run, the $animate service
-       * will examine any JavaScript-defined animations (which are defined by using the $animateProvider provider object)
-       * as well as any CSS-defined animations against the CSS classes present on the element once the DOM operation is run.
-       *
-       * The `$animate` service is used behind the scenes with pre-existing directives and animation with these directives
-       * will work out of the box without any extra configuration.
-       *
-       * Requires the {@link ngAnimate `ngAnimate`} module to be installed.
-       *
-       * Please visit the {@link ngAnimate `ngAnimate`} module overview page learn more about how to use animations in your application.
-       * ## Callback Promises
-       * With AngularJS 1.3, each of the animation methods, on the `$animate` service, return a promise when called. The
-       * promise itself is then resolved once the animation has completed itself, has been cancelled or has been
-       * skipped due to animations being disabled. (Note that even if the animation is cancelled it will still
-       * call the resolve function of the animation.)
-       *
-       * ```js
-       * $animate.enter(element, container).then(function() {
-       *   //...this is called once the animation is complete...
-       * });
-       * ```
-       *
-       * Also note that, due to the nature of the callback promise, if any Angular-specific code (like changing the scope,
-       * location of the page, etc...) is executed within the callback promise then be sure to wrap the code using
-       * `$scope.$apply(...)`;
-       *
-       * ```js
-       * $animate.leave(element).then(function() {
-       *   $scope.$apply(function() {
-       *     $location.path('/new-page');
-       *   });
-       * });
-       * ```
-       *
-       * An animation can also be cancelled by calling the `$animate.cancel(promise)` method with the provided
-       * promise that was returned when the animation was started.
-       *
-       * ```js
-       * var promise = $animate.addClass(element, 'super-long-animation').then(function() {
-       *   //this will still be called even if cancelled
-       * });
-       *
-       * element.on('click', function() {
-       *   //tooo lazy to wait for the animation to end
-       *   $animate.cancel(promise);
-       * });
-       * ```
-       *
-       * (Keep in mind that the promise cancellation is unique to `$animate` since promises in
-       * general cannot be cancelled.)

-         * | 8. $animate waits for a single animation frame (this performs a reflow)                                           | class="my-animation ng-animate ng-enter"                 |
