// MODULE: TSMapAbstract.h
//
// PURPOSE: Part of launching a Local Troubleshooter from an arbitrary NT5 application
//			Data types and abstract classes for mapping from the application's way of naming 
//			a problem to the Troubleshooter's way.
//			Implements the few concrete methods of abstract base class TSMapRuntimeAbstract.
