   * Combines the source Observable with other Observables to create an Observable
   * whose values are calculated from the latest values of each, only when the
   * source emits.
   *
   * <span class="informal">Whenever the source Observable emits a value, it
   * computes a formula using that value plus the latest values from other input
   * Observables, then emits the output of that formula.</span>
   *

   *
   * `withLatestFrom` combines each value from the source Observable (the
   * instance) with the latest values from the other input Observables only when
   * the source emits a value, optionally using a `project` function to determine
   * the value to be emitted on the output Observable. All input Observables must
   * emit at least one value before the output Observable will emit a value.
   *
   * @example <caption>On every click event, emit an array with the latest timer event plus the click event</caption>
   * var clicks = Rx.Observable.fromEvent(document, 'click');
   * var timer = Rx.Observable.interval(1000);
   * var result = clicks.withLatestFrom(timer);
   * result.subscribe(x => console.log(x));
   *
   * @see {@link combineLatest}
   *
   * @param {ObservableInput} other An input Observable to combine with the source
   * Observable. More than one input Observables may be given as argument.
   * @param {Function} [project] Projection function for combining values
   * together. Receives all values in order of the Observables passed, where the
   * first parameter is a value from the source Observable. (e.g.
   * `a.withLatestFrom(b, c, (a1, b1, c1) => a1 + b1 + c1)`). If this is not
   * passed, arrays will be emitted on the output Observable.
   * @return {Observable} An Observable of projected values from the most recent
   * values from each input Observable, or an array of the most recent values from
   * each input Observable.
   * @method withLatestFrom
   * @owner Observable
