     * Converts an ES2015 Promise or a Promises/A+ spec compliant Promise to an
     * Observable. If the Promise resolves with a value, the output Observable
     * 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));
