  *
  * Interface that classes can implement to be a data provider.
  + * A data provider class can be used with the router to resolve data during navigation.
  + * The interface defines a `resolve()` method that will be invoked when the navigation starts.
  + * The router will then wait for the data to be resolved before the route is finally activated.
  *
  * ```
  - * class Backend {
  - * fetchTeam(id: string) {
  - * return 'someTeam';
  - * }
  - * }

  - * @Injectable()
  - * class TeamResolver implements Resolve<Team> {
  - * constructor(private backend: Backend) {}

  + * export class HeroResolver implements Resolve<Hero> {

  - * return this.backend.fetchTeam(route.params.id);
