Memory Usage

All issues and bugs up to this point have been patched, specifically in 350ae55, ee3e567, and df774cc. Now a user has the ability to use node_search to accurately monitor memory usage, from not only the standpoint of total usage on a node, but the specific usage of all processes spawned from a user's job. UGE cannot see processes spawned from jobs so node_search picks up the slack allowing a user to track those processes through the --details flag.
