FUNCTION: AEEClsCreateInstance

DESCRIPTION
	This function is invoked while the app is being loaded. All Modules must provide this 
	function. Ensure to retain the same name and parameters for this function.
	In here, the module must verify the ClassID and then invoke the CGametype_New() function
	that has been provided in AEEAppGen.c. 

   After invoking AEEApplet_New(), this function can do app specific initialization. In this
   example, a generic structure is provided so that app developers need not change app specific
   initialization section every time except for a call to InitAppData(). This is done as follows:
   InitAppData() is called to initialize AppletData instance. It is app developers 
   responsibility to fill-in app data initialization code of InitAppData(). App developer
   is also responsible to release memory allocated for data contained in AppletData -- this can be
   done in FreeAppData().

PROTOTYPE:
	int AEEAppCreateInstance(AEECLSID clsID, IShell* pIShell, IModule* pIModule,IApplet** ppApplet)

PARAMETERS:
	clsID: [in]: Specifies the ClassID of the applet which is being loaded

	pIShell: [in]: Contains pointer to the IShell interface. 

	pIModule: pin]: Contains pointer to the IModule interface to the current module to which
	this app belongs

	ppApplet: [out]: On return, *ppApplet must point to a valid AEEApplet structure. Allocation
	of memory for this structure and initializing the base data members is done by AEEApplet_New().

DEPENDENCIES
  none

RETURN VALUE
  SUCCESS: If the app needs to be loaded and if AEEApplet_New() invocation was successful
  EFAILED: If the app does not need to be loaded or if errors occurred in AEEApplet_New().
  If this function returns FALSE, the app will not be loaded.

SIDE EFFECTS
  none

FUNCTION game_HandleEvent
  
DESCRIPTION
   This is the EventHandler for this app. All events to this app are handled in this
   function. All APPs must supply an Event Handler.  

   Note - The switch statement in the routine is to demonstrate how event handlers are 
   generally structured.  However, realizing the simplicity of the example, the code could
   have been reduced as follows:

   if(eCode == EVT_APP_START){
      IDISPLAY_DrawText();
      IDISPLAY_Update();
      return(TRUE);
   }
   return(FALSE);

   However, while doing so would have demonstrated how BREW apps can be written in about 8
   lines of code (including the app creation function), it might have confused those who wanted 
   a bit more practical example.

   Also note that the use of "szText" below is provided only for demonstration purposes.  As 
   indicated in the documentation, a more practical approach is to load text resources
   from the applicaton's resource file.

   Finally, note that the ONLY event that an applet must process is EVT_APP_START.  Failure
   to return TRUE from this event will indicate that the app cannot be started and BREW
   will close the applet.
    
PROTOTYPE:
   boolean game_HandleEvent(IApplet * pi, AEEEvent eCode, uint16 wParam, uint32 dwParam)
      
PARAMETERS:
   pi: Pointer to the AEEApplet structure. This structure contains information specific
   to this applet. It was initialized during the AppCreateInstance() function.
        
   ecode: Specifies the Event sent to this applet
          
   wParam, dwParam: Event specific data.
            
DEPENDENCIES
   none
              
RETURN VALUE
   TRUE: If the app has processed the event
   FALSE: If the app did not process the event
