| * <img src="./img/sample.png" width="100%"> |
| * |
| * Whenever the `notifier` Observable emits a value or completes, `sample` |
| * looks at the source Observable and emits whichever value it has most recently |
| * emitted since the previous sampling, unless the source has not emitted |
| * anything since the previous sampling. The `notifier` is subscribed to as soon |
| * as the output Observable is subscribed. |
| * |
| * @example <caption>On every click, sample the most recent "seconds" timer</caption> |
| * var seconds = Rx.Observable.interval(1000); |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var result = seconds.sample(clicks); |
| * result.subscribe(x => console.log(x)); |

| * @see {@link audit} |

| * |
| * @param {Observable<any>} notifier The Observable to use for sampling the |
| * source Observable. |
| * @return {Observable<T>} An Observable that emits the results of sampling the |
| * values emitted by the source Observable whenever the notifier Observable |
| * emits value or completes. |
