Latest population test
Calling the variables compute_ instead of titan_, so that we can use the same data structure and routines for titan and chester
Adding the node info header file for Chester. C routine is the same
The node info test is generic, so no need to lock it down to titan_node_info
Renaming to node_info_test.C and modifying the makefile appropriately
Renaming to torus_node_info.C since it is valid for all torus connected systems, so equally good for chester and titan
Changing the reference to the generic compute_node_coords
