// 	 Class : CPPTBDType
// Description : This represents a type whose exact meaning is still
//               to-be-determined.  It happens when a typename is
//               referenced in a template class (especially using the
//               'typename' keyword) but the actual type cannot be
//               known until the class is instantiated.
