| * Branch out the source Observable values as a nested Observable with each |
| * nested Observable emitting at most `windowSize` values. |

| * Observable instead of an array.</span> |

| * Returns an Observable that emits windows of items it collects from the source |
| * Observable. The output Observable emits windows every `startWindowEvery` |
| * items, each containing no more than `windowSize` items. When the source |
| * Observable completes or encounters an error, the output Observable emits |
| * the current window and propagates the notification from the source |
| * Observable. If `startWindowEvery` is not provided, then new windows are |
| * started immediately at the start of the source and when each window completes |
| * with size `windowSize`. |
| * |
| * @example <caption>Ignore every 3rd click event, starting from the first one</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var result = clicks.windowCount(3) |
| * .map(win => win.skip(1)) // skip first of every 3 clicks |
| * .mergeAll(); // flatten the Observable-of-Observables |
| * result.subscribe(x => console.log(x)); |
