Subject: -- Added many unit tests for the C parser. Almost complete now --
 Refactored project structure to allow for more overview once we add more
 languages. -- Renamed a lot of types in the CParser to be more explicit. --
 Made configuration injectable into the classes that need them. This allows to
 unit test configuration variables. -- Added 2 new config params that allows
 to customize what gets returned for a bool return type. -- Small changes to
 the logic to make it more concise.
