Class DGraph

Base class for Arbitrary-Topology Graphs. Similar structure to topology parts of DMesh3. Each vertex can be connected to an arbitrary number of edges. Each edge can have an integer GroupID. See DGraph2 and DGraph3 for 3d implementations. Use DGraphN if you would like a topology-only graph. You cannot instantiate DGraph directly.
