    this class is still under construction (especially the build features are unfinished).
    Currently, all it does is keep track of per-project views 
    (to hide or show them), define the directory when filing-out,
    and define packageName for new classes and methods.

    Future: 
	- keep track of per-project changes
	- allow speficiation of the type of the project (application, library, etc)
	- allow building of whatever the target (as defined by the type) is
	  (this will allow build of class libs and apps by clicking a button)
	- allow removal of project specific classes, methods etc.
