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.
