+ * Buffers a number of values from the source Observable by `bufferSize` then
+ * emits the buffer and clears it, and starts a new buffer each
+ * `startBufferEvery` values. If `startBufferEvery` is not provided or is
+ * `null`, then new buffers are started immediately at the start of the source
+ * and when each buffer closes and is emitted.

+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var buffered = clicks.bufferCount(2);
+ * buffered.subscribe(x => console.log(x));
+ *
+ * @example <caption>On every click, emit the last two click events as an array</caption>
