JChemPaint implements a model, controller, view (MVC) approach...

The model is defined by the core CDK data classes... these implement a
listener model, so that the view (GUI) can react on changes... The
controller is just called controller...

Originally, we just used a stack of old models (via Java cloning), but
the new API is using commands that can be undone...
