\class ModNullCallback
\brief ModNullCallback is a class containing all the callback 
functions for this demonstartion module.  These functions are 
added into the standard Audacity Project Menus.

*//*****************************************************************//**

\class ModNullCommandFunctor
\brief We create one of these functors for each menu item or 
command which we register with the Command Manager.  These take the 
click from the menu into the actual function to be called.
