Scala Runner

This app is responsible for compiling and executing Scala code. It is organized in various sub-projects:

• The server project defines a straight-forward TCP server that can receive Scala code and dependencies references, compile Scala code, and launch them by delegating to the external java command.
• The client project is an API to call the server
• The messages project defines the exchange protocol between the server and the client
• The scala-utils project defines a library that will be accessible from any Scala process launched through the runner, making it easier to share behavior between courses

The server will start on port 2003, and will store temporary files in the tmp folder of the current working directory.

Starting the docker container
