>   class ContextMenu : public CCObject

    Author:     Phil_Martin (Xara Group Ltd) <camelotdev@xara.com>
    Created:    13/03/95
    Purpose:    Encapsulate the concept of pop-up, context-sensitive menus at the kernel
                level.

                To create and use a new context-sensitive menu:
                *   Derive a new subclass from ContextMenu, e.g. ViewContextMenu.
                *   Create the operations that you want to use from the menu or use existing
                    operations.
                *   Implement a new Build function in your subclass to build your menu using
                    the helper functions provided (see func headers for more details).
                *   That's all there is to it - the menu system handles everything else!

                Note: There are guidelines about how to construct a pop-up menu and when to
                open it.
                *   The menu should be formed something like this:
                        Clicked object's primary commands
                        Clicked object's transfer commands (e.g. cut, copy, etc...)
                        "Properties..." command
                *   The menu should be opened in response to a BUTTON UP event!!!
