* Finished debugging test_new_root() in test_scan.py.
* Had to fix issues with file and path ID discrepancies between actual scan and 'theoretical scan'.
* Changed scheme to use datetime.datetime objects for LastModified and LastChecked within unit tests. Conversions are done when interacting w/ database and filesystem.
* Had to update all tests with updated IDs, BunchOfCs.txt fingerprint and new datetime.datetime. scheme.
