*
* @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=}` – An identifier name for a reference to the controller.
* 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
* `$location.path()` by applying the current route
*
* One of `template` or `templateUrl` is required.
*
* - `templateUrl` – `{(string|Function)=}` – path or function that returns a path to an html
* template that should be used by {@link ngRoute.directive:ngView ngView}.
*
* If `templateUrl` is a function, it will be called with the following parameters:
*
* - `{Array.<Object>}` - route parameters extracted from the current
* `$location.path()` by applying the current route
*
* One of `templateUrl` or `template` is required.
*
* - `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 $routeChangeError} event is fired.
* For easier access to the resolved dependencies from the template, the `resolve` map will
* be available on the scope of the route, under `$resolve` (by default) or a custom name
* specified by the `resolveAs` property (see below). This can be particularly useful, when
* working with {@link angular.Module#component components} as route templates.<br />
* <div class="alert alert-warning">
* **Note:** If your scope already contains a property with this name, it will be hidden
* or overwritten. Make sure, you specify an appropriate name for this property, that
* does not collide with other properties on the scope.
* </div>
* 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 `$route.current.params` to access the new route parameters, instead.
*
* - `resolveAs` - `{string=}` - The name under which the `resolve` map will be available on
* the scope of the route. If omitted, defaults to `$resolve`.
*
* - `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 `$location.url()`. If the function throws an error, no further processing will
* take place and the {@link ngRoute.$route#$routeChangeError $routeChangeError} event will
* be fired.
*
* Routes that specify `redirectTo` will not have their controllers, template functions
* or resolves called, the `$location` will be changed to the redirect url and route
* processing will stop. The exception to this is if the `redirectTo` is a function that
* returns `undefined`. In this case the route transition occurs as though there was no
* redirection.
*
* - `resolveRedirectTo` – `{Function=}` – a function that will (eventually) return the value
* to update {@link ng.$location $location} URL with and trigger route redirection. In
* contrast to `redirectTo`, dependencies can be injected into `resolveRedirectTo` and the
* return value can be either a string or a promise that will be resolved to a string.
*
* Similar to `redirectTo`, if the return value is `undefined` (or a promise that gets
* resolved to `undefined`), no redirection takes place and the route transition occurs as
* though there was no redirection.
*
* If the function throws an error or the returned promise gets rejected, no further
* processing will take place and the
* {@link ngRoute.$route#$routeChangeError $routeChangeError} event will be fired.
*
* `redirectTo` takes precedence over `resolveRedirectTo`, so specifying both on the same
* route definition, will cause the latter to be ignored.
*
* - `[reloadOnUrl=true]` - `{boolean=}` - reload route when any part of the URL changes
* (including the path) even if the new URL maps to the same route.
*
* If the option is set to `false` and the URL in the browser changes, but the new URL maps
* to the same route, then a `$routeUpdate` event is broadcasted on the root scope (without
* reloading the route).
*
* - `[reloadOnSearch=true]` - `{boolean=}` - reload route when only `$location.search()`
* or `$location.hash()` changes.
*
* If the option is set to `false` and the URL in the browser changes, then a `$routeUpdate`
* event is broadcasted on the root scope (without reloading the route).
*
* <div class="alert alert-warning">
* **Note:** This option has no effect if `reloadOnUrl` is set to `false`.
* </div>
*
* - `[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
