/**
 * Returns an Observable that skips items emitted by the source Observable until a second Observable emits an item.
 *
 * The `skipUntil` operator causes the observable stream to skip the emission of values ​​until the passed in observable emits the first value.
 * This can be particularly useful in combination with user interactions, responses of http requests or waiting for specific times to pass by.
 *
 * ![](skipUntil.png)
 *
 * Internally the `skipUntil` operator subscribes to the passed in observable (in the following called *notifier*) in order to recognize the emission
 * of its first value. When this happens, the operator unsubscribes from the *notifier* and starts emitting the values of the *source*
 * observable. It will never let the *source* observable emit any values if the *notifier* completes or throws an error without emitting
 * a value before.
 *
 * ## Example
 *
 * In the following example, all emitted values ​​of the interval observable are skipped until the user clicks anywhere within the page.
 *
 * ```ts
 * import { interval, fromEvent } from 'rxjs';
 * import { skipUntil } from 'rxjs/operators';
 *
 * const intervalObservable = interval(1000);
 * const click = fromEvent(document, 'click');
 *
 * const emitAfterClick = intervalObservable.pipe(
 *   skipUntil(click)
 * );
 * // clicked at 4.6s. output: 5...6...7...8........ or
 * // clicked at 7.3s. output: 8...9...10..11.......
 * const subscribe = emitAfterClick.subscribe(value => console.log(value));
 * ```
 *
 * @param {Observable} notifier - The second Observable that has to emit an item before the source Observable's elements begin to
 * be mirrored by the resulting Observable.
 * @return {Observable<T>} An Observable that skips items from the source Observable until the second Observable emits
 * an item, then emits the remaining items.
 * @method skipUntil
 * @owner Observable
