""" dabo: mainMenu.py 

    This module contains the class definitions and logic to build
    the main menu for all platforms. There are special needs for
    complying with Apple's Human Interface Guidelines, for instance.
    Also, some submenus, such as File|Open, get built dynamically
    based on menu definition files in your custom app directory
    hierarchy. The code here handles all that for you. 
    
    ToDo: make these classes easily subclassable by the custom
    app developer, so certain behavior can be overridden and/or
    extended.
