+ * Branch out the source Observable values as a nested Observable using a
+ * factory function of closing Observables to determine when to start a new
+ * window.
+ *
+ * <span class="informal">It's like {@link bufferWhen}, but emits a nested
+ * Observable instead of an array.</span>
+ *
+ * <img src="./img/windowWhen.png" width="100%">
+ *
+ * Returns an Observable that emits windows of items it collects from the source
+ * Observable. The output Observable emits connected, non-overlapping windows.
+ * It emits the current window and opens a new one whenever the Observable
+ * produced by the specified `closingSelector` function emits an item. The first
+ * window is opened immediately when subscribing to the output Observable.
+ *
+ * @example <caption>Emit only the first two clicks events in every window of [1-5] random seconds</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks
+ *   .windowWhen(() => Rx.Observable.interval(1000 + Math.random() * 4000))
+ *   .map(win => win.take(2)) // each window has at most 2 emissions
+ *   .mergeAll(); // flatten the Observable-of-Observables
+ * result.subscribe(x => console.log(x));
+ *

+ *
+ * @param {function(): Observable} closingSelector A function that takes no
+ * arguments and returns an Observable that signals (on either `next` or
+ * `complete`) when to close the previous window and start a new one.
+ * @return {Observable<Observable<T>>} An observable of windows, which in turn
+ * are Observables.
