This is based on the documentation from the Akka official site, with a couple of mixed in sources of inspiration from Here I basically used the model from there. and the publisher/subscriber implementation.
I have included some commandline argument stuff that allows you to filter the twitter stream on hash tags (there are a couple of holes on detecting hash tags that I will look into later)
You can also cleanly shut down the stream by typing exit at any point.
It also comes with SBT assembly so you can build it out into a fat jar and run it like that
The easiest way to do this though is to simply run sbt run
