/**
* The RouterLink directive lets you link to specific parts of your app.
*
* Consider the following route configuration:
* ```
* @RouteConfig([
* { path: '/user', component: UserCmp, as: 'User' }
* ]);
* class MyComp {}
* ```
*
* When linking to this `User` route, you can write:
*
* ```
* <a [routerLink]="['./User']">link to user component</a>
* ```
*
* RouterLink expects the value to be an array of route names, followed by the params
* for that level of routing. For instance `['/Team', {teamId: 1}, 'User', {userId: 2}]`
* means that we want to generate a link for the `Team` route with params `{teamId: 1}`,
* and with a child route `User` with params `{userId: 2}`.
*
* The first route name should be prepended with `/`, `./`, or `../`.
* If the route begins with `/`, the router will look up the route from the root of the app.
* If the route begins with `./`, the router will instead look in the current component's
* children for the route. And if the route begins with `../`, the router will look at the
* current component's parent.
