/**
* Skip the last `count` values emitted by the source Observable.
*
* <img src="./img/skipLast.png" width="100%">
*
* `skipLast` returns an Observable that accumulates a queue with a length
* enough to store the first `count` values. As more values are received,
* values are taken from the front of the queue and produced on the result
* sequence. This causes values to be delayed.
*
* @example <caption>Skip the last 2 values of an Observable with many values</caption>
* var many = Rx.Observable.range(1, 5);
* var skipLastTwo = many.skipLast(2);
* skipLastTwo.subscribe(x => console.log(x));
*
* // Results in:
* // 1 2 3
*
* @see {@link skip}
* @see {@link skipUntil}
* @see {@link skipWhile}
* @see {@link take}
*
* @throws {ArgumentOutOfRangeError} When using `skipLast(i)`, it throws
* ArgumentOutOrRangeError if `i < 0`.
*
* @param {number} count Number of elements to skip from the end of the source Observable.
* @returns {Observable<T>} An Observable that skips the last count values
* emitted by the source Observable.
* @method skipLast
* @owner Observable
