Scala port

[jchapuis]

Hello there, just wanted to give a heads-up here that I've started an effort on porting SimPy's process-oriented approach to the scala/akka platform.

You can see some (very early) results here: https://github.com/jchapuis/simscala

We have a need for such a platform at my current workplace and so I took advantage of this opportunity to launch this project - I hope we will end up using it and that I'll have more time to work on it.

Any suggestions or help welcome!
