// The CEmptyComponent class is an skeletal version of a component
// It is intended that you use this as the basis for creating new
// components.  
// To create a new component called "Watch", (CWatchComponent):
//  - copy emptycomponent.cpp/.h to watchcomponent.cpp/.h
//  - in both files, search and replace "Empty" with "Watch", preserving the case
//  - in WatchComponent.h, update the CRCD value of CRC_WATCH
//  - in CompositeObjectManager.cpp, in the CCompositeObjectManager constructor, add:
//		  	RegisterComponent(CRC_WATCH,			CWatchComponent::s_create); 
//  - and add the include of the header
//			#include <gel/components/watchcomponent.h> 
//  - Add it to build\gel.mkf, like:
//          $(NGEL)/components/WatchComponent.cpp\
//  - Fill in the OWNER (yourself) and the CREATION DATE (today's date) in the .cpp and the .h files
//	- Insert code as needed and remove generic comments
//  - remove these comments
//  - add comments specfic to the component, explaining its usage
