/**
* @assertion Stream.fromFutures(Iterable<Future<T>> futures)
* Create a stream from a group of futures.
* The stream reports the results of the futures on the stream in the order
* in which the futures complete.
* If some futures have completed before calling Stream.fromFutures,
* their result will be output on the created stream in some unspecified order.
* When all futures have completed, the stream is closed.
* If no future is passed, the stream closes as soon as possible.
* @description Checks Stream interface methods
