   *
   * Buffers values from the source by opening the buffer via signals from an
   * Observable provided to `openings`, and closing and sending the buffers when
   * a Subscribable or Promise returned by the `closingSelector` function emits.
   *
   * @example <caption>Every other second, emit the click events from the next 500ms</caption>
   * var clicks = Rx.Observable.fromEvent(document, 'click');
   * var openings = Rx.Observable.interval(1000);
   * var buffered = clicks.bufferToggle(openings, i =>
   *   i % 2 ? Rx.Observable.interval(500) : Rx.Observable.empty()
   * );
   * buffered.subscribe(x => console.log(x));

   * @param {SubscribableOrPromise<O>} openings A Subscribable or Promise of notifications to start new

   * @param {function(value: O): SubscribableOrPromise} closingSelector A function that takes
   * the value emitted by the `openings` observable and returns a Subscribable or Promise,
   * which, when it emits, signals that the associated buffer should be emitted
   * and cleared.
   * @return {Observable<T[]>} An observable of arrays of buffered values.
