Promising Future

This crate implements Promises and Futures, where a Future represents an unknown value, and a Promise determines what that value is.

It also provides FutureStream which allows multiple Futures to be waited on, yielding values as they become available.

While this could be seen as a "yet another" crate, the API both simpler and more general than other implementations of Futures, and more easily composable.
