SBTEclipse creates and updates Scala IDE projects that use an SBT build file.

We learned about the Actor model, a model where various actors send messages to each other. Each actor has a single method that handles all the messages. Instead of communicating directly with actor instances, actor references called ActorRef instances are used. If you use ActorRef instances, the code wouldn't care much whether an actor is running locally or remotely on a network. We wrote a unit test using a DSL to test the internals of an actor. Finally, we wrote the main program that used ask-pattern and Future objects to wait for replies.
