// Revision: A
//
// Purpose: This file contains the class definition for DummyNode.
// DummyNodes are a type of node created and used by Subdomains for their
// exterior nodes. They reference a real node and most methods invoked on
// them are in turn invoked by the dummy node on the real node. The calls
// asking the real node to change its current state are ignored. The
// calls involving DOF\_Group are handled by the dummy node.
//
// 
// What: "@(#) DummyNode.h, revA"
