     * Converts an ES2015 Promise or a Promises/A+ spec compliant Promise to an

     * emits that resolved value as a `next`, and then completes. If the Promise

     * @example <caption>Convert the Promise returned by Fetch to an Observable</caption>
     * var result = Rx.Observable.fromPromise(fetch('http://myserver.com/'));
     * result.subscribe(x => console.log(x), e => console.error(e));

     * the delivery of the resolved value (or the rejection).
     * @return {Observable<T>} An Observable which wraps the Promise.
