// Description:
// TCon3 is a simple test conarc plug-in used by the test program TExtInterface
// The idea of this plug in is to provide several 'extended interfaces' which get
// instantiated via CConverterBase2::ExtendedInterfaceL
// These extended interfaces are defined by several abstract base classes below. 
// Derived clases provide concrete implementations of these classes in TCon3.cpp 
// 
//
