/**
 * @name Deeplinks
 * @description This plugin handles deeplinks on iOS and Android for both custom URL scheme links
 * and Universal App Links.
 *
 * @usage
 * ```typescript
 * import { Deeplinks } from '@ionic-native/deeplinks';
 *
 * constructor(private deeplinks: Deeplinks) { }
 *
 * this.deeplinks.route({
 *      '/about-us': AboutPage,
 *      '/universal-links-test': AboutPage,
 *      '/products/:productId': ProductPage
 *    }).subscribe((match) => {
 *      // match.$route - the route we matched, which is the matched entry from the arguments to route()
 *      // match.$args - the args passed in the link
 *      // match.$link - the full link data
 *      console.log('Successfully matched route', match);
 *    }, (nomatch) => {
 *      // nomatch.$link - the full link data
 *      console.error('Got a deeplink that didn\'t match', nomatch);
 *    });
 * ```
 *
 * Alternatively, if you're using Ionic 2, there's a convenience method that takes a reference to a `NavController` and handles
 * the actual navigation for you:
 *
 * ```typescript
 * this.deeplinks.routeWithNavController(this.navController, {
 *   '/about-us': AboutPage,
 *   '/products/:productId': ProductPage
 * }).subscribe((match) => {
 *     // match.$route - the route we matched, which is the matched entry from the arguments to route()
 *     // match.$args - the args passed in the link
 *     // match.$link - the full link data
 *     console.log('Successfully matched route', match);
 *   }, (nomatch) => {
 *     // nomatch.$link - the full link data
 *     console.error('Got a deeplink that didn\'t match', nomatch);
 *   });
 * ```
 *
 * See the [Ionic 2 Deeplinks Demo](https://github.com/driftyco/ionic2-deeplinks-demo/blob/master/app/app.ts) for an example of how to
 * retrieve the `NavController` reference at runtime.
