Starting to work on multi-test run framework. Initial commit. Functionallity in run_player.py is being pushed in setup_util.py so that Overlord can use it.

Oh right. Overlord is what I'm calling the program that is going to coordinate the running of the experiment. Overlord reads information about the experiment from the .ini file, which describes files, controllers, and results (still working on this bit).
Small changes. Overlord now has the same functionality as run_player.py.
Minor tweak. Mostly notes.
