+ * Branch out the source Observable values as a nested Observable with each
+ * nested Observable emitting at most `windowSize` values.
+ *
+ * <span class="informal">It's like {@link bufferCount}, but emits a nested
+ * Observable instead of an array.</span>

+ * <img src="./img/windowCount.png" width="100%">
+ *
+ * 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));
+ *
+ * @example <caption>Ignore every 3rd click event, starting from the third one</caption>

+ * @param {number} windowSize The maximum number of values emitted by each

+ * on every other value from the source. A new window is started at the
+ * beginning of the source by default.
+ * @return {Observable<Observable<T>>} An Observable of windows, which in turn
+ * are Observable of values.
