Plugin updated + Typers for tests

- Main execusion of the plugin modified to take the name of the source. Will
	have to be adapted a bit later.
- Put Decomposer and Recomposer as object, since they are just applied.
- Cleaning of some comments + TODOs
- Addition of Typers in sandbox/ for compilation. Also added the dependencies
	to compile with the Scala Internals.
