   * @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.

 * @description
 * 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
 *  //

 *
 * 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.
