Class Description

 This class provides an interface to  context sensitive popup menus.  
 These menus pop up when the user hits the right mouse button, and    
 are destroyed when the menu pops downs.                              
                                                                      
 Context Menus are automatically generated by ROOT using the          
 following convention: if the string // *MENU* is found in the        
 comment field of a member function. This function will be added to   
 the list of items in the menu.                                       
                                                                      
 The picture below shows a canvas with a pop-up menu.                 
                                                                      
                        
                                                                      
 The picture below shows a canvas with a pop-up menu and a dialog box.
