Basic plugin framework architecture

   1. Program initialized.
   2. On_Init looks for plug-ins and so forth.
   3. Program calls a method named "load" on each plugin found.
   4. After load is called, program caches the name of each module and creates a reference so that the functions in this plug-in can be called later.
   5. During the course of running the program, the user selects one of the menu items, and one of a set of clearly defined standard methods are invoked.
   6. Upon shutdown of program, a method called "unload" will be called to free the resources, which were allocated in the "load" method.
