// Description: This file contains the class definition for MeshRegion.
// A Region is a part of the domain which is defined by a set of
// Elements and Nodes (all the end nodes of the elements are in the region, 
// as are all elements whose end nodes are in the region)
//
// What: "@(#) Region.h, revA"
