*
* @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
* `$routeUpdate` event is broadcasted on the root scope.
*
* - `[caseInsensitiveMatch=false]` - {boolean=} - match routes without being case sensitive
*
* If the option is set to `true`, then the particular route can be matched without being
* case sensitive
*
* @returns {Object} self
*
* @description
* Adds a new route definition to the `$route` service.

* `$route` is used for deep-linking URLs to controllers and views (HTML partials).
* It watches `$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.
