//Description:
//
// This file contains the class definition for the most fundammental
//DPT engine class dptCore_C.

//Class - dptCore_C - start
//===========================================================================
//
//Description:
//
// This is the most fundamental class in the DPT class hiearchy.
//All objects in the DPT engine should have this class as the
//ultimate ancestor.
//
//Remarks: (Side effects, Assumptions, Warnings...)
//
// 1. No error checking is performed on the tag counter.
// If the tag counter were to wrap around to zero,
// their could potentially be objects with the same tag #
// which could result in the wrong object recieving an
// event. This tag is not checked for wrap around
// because it was originally implemented as a 32 bit counter
// and the author assumed there would never be more than
// 4 G objects created during the course of an application.
//
