Detailed Description

Author: Abhinav S Bhatele Date Created: March 19th, 2007.

This would be the top level interface for all topology managers we will write for different machines (Cray, IBM ... for tori, meshes ...) Current we have functionality for Blue Gene, Cray XT, BigSim and non-topo machines.
