Demos added
Removing unused imports
Ported towards new jDEECo
New folder jdeeco-concepts added. Here are stored ideas and concepts
that would be nice to have but current jDEECo does not allow them to be
coded(well, properly at least). Also project 'parkinglotbooking' was
removed from jdeeco-demos and moved to jdeeco-concepts.
All projects moved to new jdeeco successfully(with jpf ignored).
All potred to jdeeco 2.0.0
