// COM1205 Propagation Pattern for DemDraw Project.
//
// Created by Young Soo Yang (yyang@ccs.neu.edu)
//
// This file contains 4 propagation patterns,
// cppCompEdgeName(), cppSetEdgeName(), cppCompVertName(), & cppSetVertName().
//
// They are called by other propagation patterns such as cppRenEdge(),
// cppRenVertex(), cppDelVertex(), cppDelAEdge(), & cppDelCEdge() that need
// to access label names of vertices and edges to check or reset the names
// of them.
//
// Modification History:
//
// 11/26/95 - Young Soo Yang (yyang@ccs.neu.edu)
//	First created to support and make other propagation patterns more
//	structure shy.
//


// This will compare a label name of a construction edge with the argument
// Labelname and returns 1 if they are same, otherwise, returns 0.
