PROGRAM: Generic.c
PURPOSE: Generic template for Windows applications
FUNCTIONS:
WinMain() - calls initialization function, processes message loop
InitApplication() - initializes window data and registers window
InitInstance() - saves instance handle and creates main window
WndProc() - processes messages
CenterWindow() - used to center the "About" box over application window
About() - processes messages for "About" dialog box
COMMENTS:
The Windows SDK Generic Application Example is a sample application
that you can use to get an idea of how to perform some of the simple
functionality that all Applications written for Microsoft Windows
should implement. You can use this application as either a starting
point from which to build your own applications, or for quickly
testing out functionality of an interesting Windows API.
This application is source compatible for with Windows 3.1 and
Windows NT.

FUNCTION: WinMain(HINSTANCE, HINSTANCE, LPTSTR, 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.

FUNCTION: InitApplication(HINSTANCE)
PURPOSE: Initializes window data and registers window class
COMMENTS:
This function is called at initialization time only if no other
instances of the application are running. This function performs
initialization tasks that can be done once for any number of running
instances.
In this case, we initialize a window class by filling out a data
structure of type WNDCLASS and calling the Windows RegisterClass()
function. Since all instances of this application use the same window
class, we only need to do this when the first instance is initialized.

PURPOSE: Saves instance handle and creates main window
COMMENTS:
This function is called at initialization time for every instance of
