Hi again,

I have updated the README with a second, bigger example showing also the use of continuations, when_all and when_any.

On a second thought, maybe I could even change the implementation of the future_queue to internally use e.g. the well-known boost::lockfree queues together with some semaphore to implement the blocking behaviour. I am not 100% sure yet, but I think all current features could be implemented by that. Do you think this would improve the implementation? It might be a bit simpler and maybe even more efficient in some cases.

Cheers,
Martin
