Modules/Postprocessing is done in LiveScript

[LittleHelicase]

Module implementations and postprocessings currently support only LiveScript implementations. They should be pure Buggy implementations to avoid Module/Postprocessing dependencies twoard LiveScript or any other language. This is probably not possible until Buggy is capable of more advanced stuff.

• The processing of modules is located at src/resolve.ls
• The evaluation of postprocessing modules is located at src/compose/postprocess.ls
