First 'real' edits.
- Documented, implemented getters, setters, checkers for the various
  variables of the worm.
- Changes to Facade to handle exceptions (although not sure if this is
  the correct way)
- Includes 'Notes.txt' for collection and exchange of notes, remarks
  questions, ... (also for the consultancy sessions) Also see TODOs in
  the body of the class.
- Deleted src-provided (gives Eclipse errors).

Will contain errors. :)
