* Creates an Observable that emits sequential numbers every specified

*
* `interval` returns an Observable that emits an infinite sequence of
* ascending integers, with a constant interval of time of your choosing
* between those emissions. The first emission is not sent immediately, but
* only after the first period has passed. By default, this operator uses the
* `async` IScheduler to provide a notion of time, but you may pass any
* IScheduler to it.
*
* @example <caption>Emits ascending numbers, one every second (1000ms)</caption>
* var numbers = Rx.Observable.interval(1000);
* numbers.subscribe(x => console.log(x));
*
* @see {@link timer}
* @see {@link delay}
*
* @param {number} [period=0] The interval size in milliseconds (by default)
* or the time unit determined by the scheduler's clock.
* @param {Scheduler} [scheduler=async] The IScheduler to use for scheduling
* the emission of values, and providing a notion of "time".
* @return {Observable} An Observable that emits a sequential number each time
* interval.
* @static true
* @name interval
