//  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
