| * Buffers values from the source by opening the buffer via signals from an |

| * a Subscribable or Promise returned by the `closingSelector` function emits. |
| * |
| * @example <caption>Every other second, emit the click events from the next 500ms</caption> |
| * var clicks = Rx.Observable.fromEvent(document, 'click'); |
| * var openings = Rx.Observable.interval(1000); |
| * var buffered = clicks.bufferToggle(openings, i => |
| * i % 2 ? Rx.Observable.interval(500) : Rx.Observable.empty() |

| * and cleared. |
