/**
 * Add here external dependencies that actually you use.
 *
 * About RxJS
 * Each RxJS functionality that you use in the library must be added as external dependency.
 * - For main classes use 'Rx':
 *      e.g. import { Observable } from 'rxjs/Observable'; => 'rxjs/Observable': 'Rx'
 * - For observable methods use 'Rx.Observable':
 *      e.g. import 'rxjs/add/observable/merge'; => 'rxjs/add/observable/merge': 'Rx.Observable'
 *      or for lettable operators:
 *      e.g. import { merge } from 'rxjs/observable/merge'; => 'rxjs/observable/merge': 'Rx.Observable'
 * - For operators use 'Rx.Observable.prototype':
 *      e.g. import 'rxjs/add/operator/map'; => 'rxjs/add/operator/map': 'Rx.Observable.prototype'
 *      or for lettable operators:
 *      e.g. import { map } from 'rxjs/operators'; => 'rxjs/operators': 'Rx.Observable.prototype'
