This patch makes the internal links within the network topology unidirectional, thus allowing any deadlock-free routing algorithms to be specified from the topology itself using weights. This patch also renames Mesh.py and MeshDirCorners.py to Mesh_XY.py and MeshDirCorners_XY.py (Mesh with XY routing). It also adds a Mesh_westfirst.py and CrossbarGarnet.py topologies.
