/**
 * \@whatItDoes Lets you link to specific parts of your app.
 *
 * \@howToUse
 *
 * Consider the following route configuration:
 * `[{ path: 'user/:name', component: UserCmp }]`
 *
 * When linking to this `user/:name` route, you can write:
 * `<a routerLink='/user/bob'>link to user component</a>`
 *
 * \@description
 *
 * The RouterLink directives let you link to specific parts of your app.
 *
 * When the link is static, you can use the directive as follows:
 * `<a routerLink="/user/bob">link to user component</a>`
 *
 * If you use dynamic values to generate the link, you can pass an array of path
 * segments, followed by the params for each segment.
 *
 * For instance `['/team', teamId, 'user', userName, {details: true}]`
 * means that we want to generate a link to `/team/11/user/bob;details=true`.
 *
 * Multiple static segments can be merged into one
 * (e.g., `['/team/11/user', userName, {details: true}]`).
 *
 * The first segment name can be prepended with `/`, `./`, or `../`:
 * * If the first segment begins with `/`, the router will look up the route from the root of the
 *   app.
 * * If the first segment begins with `./`, or doesn't begin with a slash, the router will
 *   instead look in the children of the current activated route.
 * * And if the first segment begins with `../`, the router will go up one level.
 *
 * You can set query params and fragment as follows:
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" fragment="education">
 *   link to user component
 * </a>
 * ```
 * RouterLink will use these to generate this link: `/user/bob#education?debug=true`.
 *
 * (Deprecated in v4.0.0 use `queryParamsHandling` instead) You can also tell the
 * directive to preserve the current query params and fragment:
 *
 * ```
 * <a [routerLink]="['/user/bob']" preserveQueryParams preserveFragment>
 *   link to user component
 * </a>
 * ```
 *
 * You can tell the directive to how to handle queryParams, available options are:
 *  - 'merge' merge the queryParams into the current queryParams
 *  - 'preserve' prserve the current queryParams
 *  - default / '' use the queryParams only
 *  same options for {\@link NavigationExtras.queryParamsHandling}
 *
 * ```
 * <a [routerLink]="['/user/bob']" [queryParams]="{debug: true}" queryParamsHandling="merge">
 *   link to user component
 * </a>
 * ```
 *
 * The router link directive always treats the provided input as a delta to the current url.
 *
 * For instance, if the current url is `/user/(box//aux:team)`.
 *
 * Then the following link `<a [routerLink]="['/user/jim']">Jim</a>` will generate the link
 * `/user/(jim//aux:team)`.
 *

 *
 * The RouterLinkActive directive lets you add a CSS class to an element when the link's route
 * becomes active.
 *
 * Consider the following example:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link">Bob</a>
 * ```
 *
 * When the url is either '/user' or '/user/bob', the active-link class will
 * be added to the `a` tag. If the url changes, the class will be removed.
 *
 * You can set more than one class, as follows:
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="class1 class2">Bob</a>
 * <a routerLink="/user/bob" [routerLinkActive]="['class1', 'class2']">Bob</a>
 * ```
 *
 * You can configure RouterLinkActive by passing `exact: true`. This will add the classes
 * only when the url matches the link exactly.
 *
 * ```
 * <a routerLink="/user/bob" routerLinkActive="active-link" [routerLinkActiveOptions]="{exact:
 * true}">Bob</a>
 * ```
 *
 * You can assign the RouterLinkActive instance to a template variable and directly check
 * the `isActive` status.
 * ```
 * <a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive">
 *   Bob {{ rla.isActive ? '(already open)' : ''}}
 * </a>
 * ```
 *
 * Finally, you can apply the RouterLinkActive directive to an ancestor of a RouterLink.
 *
 * ```
 * <div routerLinkActive="active-link" [routerLinkActiveOptions]="{exact: true}">
 *   <a routerLink="/user/jim">Jim</a>
 *   <a routerLink="/user/bob">Bob</a>
 * </div>
 * ```
 *
 * This will set the active-link class on the div tag if the url is either '/user/jim' or
 * '/user/bob'.

/**
 * \@whatItDoes Adds router directives and providers.
 *
 * \@howToUse
 *
 * RouterModule can be imported multiple times: once per lazily-loaded bundle.
 * Since the router deals with a global shared resource--location, we cannot have
 * more than one router service active.
 *
 * That is why there are two ways to create the module: `RouterModule.forRoot` and
 * `RouterModule.forChild`.
 *
 * * `forRoot` creates a module that contains all the directives, the given routes, and the router
 *   service itself.
 * * `forChild` creates a module that contains all the directives and the given routes, but does not
 *   include the router service.
 *
 * When registered at the root, the module should be used as follows
 *
 * ```
 * \@NgModule({
 *   imports: [RouterModule.forRoot(ROUTES)]
 * })
 * class MyNgModule {}
 * ```
 *
 * For submodules and lazy loaded submodules the module should be used as follows:
 *
 * ```
 * \@NgModule({
 *   imports: [RouterModule.forChild(ROUTES)]
 * })
 * class MyNgModule {}
 * ```
 *
 * \@description
 *
 * Managing state transitions is one of the hardest parts of building applications. This is
 * especially true on the web, where you also need to ensure that the state is reflected in the URL.
 * In addition, we often want to split applications into multiple bundles and load them on demand.
 * Doing this transparently is not trivial.
 *
 * The Angular router solves these problems. Using the router, you can declaratively specify
 * application states, manage state transitions while taking care of the URL, and load bundles on
 * demand.
 *
 * [Read this developer guide](https://angular.io/docs/ts/latest/guide/router.html) to get an
 * overview of how the router should be used.
