| * Branch out the source Observable values as a nested Observable whenever |

| * 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 `windowBoundaries` emits an item. Because each window is an |
| * Observable, the output is a higher-order Observable. |
| * |
| * @example <caption>In every window of 1 second each, emit at most 2 click events</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var interval = Rx.Observable.interval(1000); |
| * var result = clicks.window(interval) |
| * .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 {Observable<any>} windowBoundaries An Observable that completes the |
