Merge branch 'master' of github.com:CS533-Winter2013-Group4/PerfTrack

Conflicts:
	src/dataStore/PTds.py

Updates to ptdf_entry to use cached queries when possible improving performance up to 2x.
Updates to testing scripts to actually run.
Added scripts/run_tests.py that runs all the tests (most of which fail) but does give some level of correctness testing.
Removed some generated test files from PTdFTestGenData.
