* Buffers the source Observable values, using a factory function of closing
* Observables to determine when to close, emit, and reset the buffer.

* <span class="informal">Collects values from the past as an array. When it
* starts collecting values, it calls a function that returns an Observable that
* tells when to close the buffer and restart collecting.</span>

* Opens a buffer immediately, then closes the buffer when the observable
* returned by calling `closingSelector` function emits a value. When it closes
* the buffer, it immediately opens a new buffer and repeats the process.
*
* @example <caption>Emit an array of the last clicks every [1-5] random seconds</caption>
* var clicks = Rx.Observable.fromEvent(document, 'click');
* var buffered = clicks.bufferWhen(() =>
* Rx.Observable.interval(1000 + Math.random() * 4000)
* );
* buffered.subscribe(x => console.log(x));
