+   * @ngdoc method

+   *
+   * @param {string} path Route path (matched against `$location.path`). If `$location.path`
+   *    contains redundant trailing slash or is missing one, the route will still match and the
+   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
+   *    route definition.
+   *
+   *    * `path` can contain named groups starting with a colon: e.g. `:name`. All characters up
+   *        to the next slash are matched and stored in `$routeParams` under the given `name`
+   *        when the route matches.
+   *    * `path` can contain named groups starting with a colon and ending with a star:
+   *        e.g.`:name*`. All characters are eagerly stored in `$routeParams` under the given `name`
+   *        when the route matches.
+   *    * `path` can contain optional named groups with a question mark: e.g.`:name?`.
+   *
+   *    For example, routes like `/color/:color/largecode/:largecode*\/edit` will match
+   *    `/color/brown/largecode/code/with/slashes/edit` and extract:
+   *
+   *    * `color: brown`
+   *    * `largecode: code/with/slashes`.
+   *
+   *
+   * @param {Object} route Mapping information to be assigned to `$route.current` on route
+   *    match.
+   *
+   *    Object properties:
+   *
+   *    - `controller` – `{(string|function()=}` – Controller fn that should be associated with
+   *      newly created scope or the name of a {@link angular.Module#controller registered
+   *      controller} if passed as a string.
+   *    - `controllerAs` – `{string=}` – A controller alias name. If present the controller will be
+   *      published to scope under the `controllerAs` name.
+   *    - `template` – `{string=|function()=}` – html template as a string or a function that
+   *      returns an html template as a string which should be used by {@link
+   *      ngRoute.directive:ngView ngView} or {@link ng.directive:ngInclude ngInclude} directives.
+   *      This property takes precedence over `templateUrl`.
+   *
+   *      If `template` is a function, it will be called with the following parameters:
+   *
+   *      - `{Array.<Object>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route
+   *
+   *    - `templateUrl` – `{string=|function()=}` – path or function that returns a path to an html
+   *      template that should be used by {@link ngRoute.directive:ngView ngView}.
+   *
+   *      If `templateUrl` is a function, it will be called with the following parameters:
+   *
+   *      - `{Array.<Object>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route
+   *
+   *    - `resolve` - `{Object.<string, function>=}` - An optional map of dependencies which should
+   *      be injected into the controller. If any of these dependencies are promises, the router
+   *      will wait for them all to be resolved or one to be rejected before the controller is
+   *      instantiated.
+   *      If all the promises are resolved successfully, the values of the resolved promises are
+   *      injected and {@link ngRoute.$route#$routeChangeSuccess $routeChangeSuccess} event is
+   *      fired. If any of the promises are rejected the
+   *      {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired. The map object
+   *      is:
+   *
+   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
+   *      - `factory` - `{string|function}`: If `string` then it is an alias for a service.
+   *        Otherwise if function, then it is {@link auto.$injector#invoke injected}
+   *        and the return value is treated as the dependency. If the result is a promise, it is
+   *        resolved before its value is injected into the controller. Be aware that
+   *        `ngRoute.$routeParams` will still refer to the previous route within these resolve
+   *        functions.  Use `$route.current.params` to access the new route parameters, instead.
+   *
+   *    - `redirectTo` – {(string|function())=} – value to update
+   *      {@link ng.$location $location} path with and trigger route redirection.
+   *
+   *      If `redirectTo` is a function, it will be called with the following parameters:
+   *
+   *      - `{Object.<string>}` - route parameters extracted from the current
+   *        `$location.path()` by applying the current route templateUrl.
+   *      - `{string}` - current `$location.path()`
+   *      - `{Object}` - current `$location.search()`
+   *
+   *      The custom `redirectTo` function is expected to return a string which will be used
+   *      to update `$location.path()` and `$location.search()`.
+   *
+   *    - `[reloadOnSearch=true]` - {boolean=} - reload route when only `$location.search()`
+   *      or `$location.hash()` changes.
+   *
+   *      If the option is set to `false` and url in the browser changes, then
+   *      `$routeUpdate` event is broadcasted on the root scope.
+   *
+   *    - `[caseInsensitiveMatch=false]` - {boolean=} - match routes without being case sensitive
+   *
+   *      If the option is set to `true`, then the particular route can be matched without being
+   *      case sensitive
+   *
+   * @returns {Object} self

+     * @description
+     * `$route` is used for deep-linking URLs to controllers and views (HTML partials).
+     * It watches `$location.url()` and tries to map the path to an existing route definition.
+     *
+     * Requires the {@link ngRoute `ngRoute`} module to be installed.
+     *
+     * You can define routes through {@link ngRoute.$routeProvider $routeProvider}'s API.
+     *
+     * The `$route` service is typically used in conjunction with the
+     * {@link ngRoute.directive:ngView `ngView`} directive and the
+     * {@link ngRoute.$routeParams `$routeParams`} service.
+     *
+     * @example
+     * This example shows how changing the URL hash causes the `$route` to match a route against the
+     * URL, and the `ngView` pulls in the partial.
+     *
+     * Note that this example is using {@link ng.directive:script inlined templates}
+     * to get it working on jsfiddle as well.

+ * The `$routeParams` service allows you to retrieve the current set of route parameters.
+ *
+ * Requires the {@link ngRoute `ngRoute`} module to be installed.
+ *
+ * The route parameters are a combination of {@link ng.$location `$location`}'s
+ * {@link ng.$location#search `search()`} and {@link ng.$location#path `path()`}.
+ * The `path` parameters are extracted when the {@link ngRoute.$route `$route`} path is matched.
+ *
+ * In case of parameter name collision, `path` params take precedence over `search` params.
+ *
+ * The service guarantees that the identity of the `$routeParams` object will remain unchanged
+ * (but its properties will likely change) even when a route change occurs.
+ *
+ * Note that the `$routeParams` are only updated *after* a route change completes successfully.
+ * This means that you cannot rely on `$routeParams` being correct in route resolve functions.
+ * Instead you can use `$route.current.params` to access the new route's parameters.
+ *
+ * @example
+ * ```js
+ *  // Given:
+ *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
+ *  // Route: /Chapter/:chapterId/Section/:sectionId
+ *  //

+ * @ngdoc directive
+ * @name ngView
+ * @restrict ECA
+ *
+ * @description
+ * # Overview
+ * `ngView` is a directive that complements the {@link ngRoute.$route $route} service by
+ * including the rendered template of the current route into the main layout (`index.html`) file.
+ * Every time the current route changes, the included view changes with it according to the
+ * configuration of the `$route` service.
+ *
+ * Requires the {@link ngRoute `ngRoute`} module to be installed.
+ *
+ * @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.
+ *
+ * @scope
+ * @priority 400
+ * @param {string=} onload Expression to evaluate whenever the view updates.
+ *
+ * @param {string=} autoscroll Whether `ngView` should call {@link ng.$anchorScroll
+ *                  $anchorScroll} to scroll the viewport after the view is updated.
+ *
+ *                  - If the attribute is not set, disable scrolling.
+ *                  - If the attribute is set without value, enable scrolling.
+ *                  - Otherwise enable scrolling only if the `autoscroll` attribute value evaluated
+ *                    as an expression yields a truthy value.
