    FUNCTION: WinMain(HANDLE, HANDLE, LPSTR, int)

    PURPOSE: calls initialization function, processes message loop

    COMMENTS:

        Windows recognizes this function by name as the initial entry point
        for the program.  This function calls the application initialization
        routine, if no other instance of the program is running, and always
        calls the instance initialization routine.  It then executes a message
        retrieval and dispatch loop that is the top-level control structure
        for the remainder of execution.  The loop is terminated when a WM_QUIT
        message is received, at which time this function exits the application
        instance by returning the value passed by PostQuitMessage().

        If this function must abort before entering the message loop, it
        returns the conventional value NULL.

        structure of type WNDCLASS and calling the Windows RegisterClass()
        function.  Since all instances of this application use the same window
