/**
 * Emits the most recently emitted value from the source Observable within
 * periodic time intervals.
 *
 * <span class="informal">Samples the source Observable at periodic time
 * intervals, emitting what it samples.</span>
 *
 * <img src="./img/sampleTime.png" width="100%">
 *
 * `sampleTime` periodically 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 sampling
 * happens periodically in time every `period` milliseconds (or the time unit
 * defined by the optional `scheduler` argument). The sampling starts as soon as
 * the output Observable is subscribed.
 *
 * @example <caption>Every second, emit the most recent click at most once</caption>
 * var clicks = Rx.Observable.fromEvent(document, 'click');
 * var result = clicks.sampleTime(1000);
 * result.subscribe(x => console.log(x));
 *
 * @see {@link auditTime}
 * @see {@link debounceTime}
 * @see {@link delay}
 * @see {@link sample}
 * @see {@link throttleTime}
 *
 * @param {number} period The sampling period expressed in milliseconds or the
 * time unit determined internally by the optional `scheduler`.
 * @param {Scheduler} [scheduler=async] The {@link IScheduler} to use for
 * managing the timers that handle the sampling.
 * @return {Observable<T>} An Observable that emits the results of sampling the
 * values emitted by the source Observable at the specified time interval.
 * @method sampleTime
 * @owner Observable
