-To define a new kind of module, derive a class from wxModule, override the OnInit and OnExit functions,
-and add the DECLARE\_DYNAMIC\_CLASS and IMPLEMENT\_DYNAMIC\_CLASS to header and implementation files
-(which can be the same file). On initialization, wxWidgets will find all classes derived from wxModule,
-create an instance of each, and call each OnInit function. On exit, wxWidgets will call the OnExit
-function for each module instance.

 Note that your module class does not have to be in a header file.
