   Module  Name :

        useropt.h

   Abstract:

        Global user options class and help class implementations. This class 
		can only instantiate by CLinkCheckerMgr. Therefore, a single instance 
		of this class will live inside CLinkCheckerMgr. You can access
		the this instance by calling GetLinkCheckMgr().GetUserOptions().
