/** \class TPaveClass
\ingroup gpad
 
A TPaveLabel specialized to process classes inside a TClassTree.
A TPaveClass object is used by the TClassTree to represent a class.
A TPaveClass has the same graphical representation as a TPaveLabel.
 
Using the context menu on can select additional options in the ClassTree:
  - Show classes using this class
  - Show all classes used by this class
