* Buffers the source Observable values starting from an emission from |

|
* <span class="informal">Collects values from the past as an array. Starts |

|
* Buffers values from the source by opening the buffer via signals from an |
|
* Observable provided to `openings`, and closing and sending the buffers when |
|
* 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() |
|
* ); |
|
* buffered.subscribe(x => console.log(x)); |

* @param {SubscribableOrPromise<O>} openings A Subscribable or Promise of notifications to start new |

|
* @param {function(value: O): SubscribableOrPromise} closingSelector A function that takes |
|
* the value emitted by the `openings` observable and returns a Subscribable or Promise, |
|
* which, when it emits, signals that the associated buffer should be emitted |
|
* and cleared. |
|
* @return {Observable<T[]>} An observable of arrays of buffered values. |
