+// Description:
+// A revised version of the CRegisteredParserDll class.  This no longer uses a 
+// reference to a CParserRegistrationData object.  Instead a UidType is passed in 
+// the  constructor, or through a set method.  The class is used to find the file 
+// which contains a parser, to load and maintain a reference count of the number of 
+// objects using the dll, so that it can be unloaded when no longer required. 
+// It will also unload the dll when a new parser is required.
+//
