>   Class MenuItem : public Control

    Author:     Mario_Shamtani (Xara Group Ltd) <camelotdev@xara.com>
    Created:    16/6/93
    Purpose:    
        MenuItems are the things that appear in menus, but in camelot they are also the menus 
        themselves. The idea is that the menu system is a dynamically growing, living-thing 
        where all the elements are connected in a tree like structure. The elements of the 
        menu system or the nodes in the tree are MenuItems. MenuItems can therefore be 
        simple or composite i.e. a menu option or a sub menu. In windows there is a third 
        type of MenuItem: the separator, in our new improved menuing system separators will
        not be modelled as MenuItems. Instead a MenuItem may be specified as having a menu 
        separator following it.  
    Errors:     None yet.
