Modified GUFI driver and added Test

[hugegreenbug]

Changed GUFI driver to use the new FsStore abstract class
Changed the GUFI query command to use a dsi db, dsi db table, and a dsi db column for joining with GUFI metadata
Added a GUFI test

This brings up a good question. How do we handle plugin and driver testing if plugins and drivers are compiled tools? I opened #33 to track this concern, but resolution is not required for merging this PR. Just pick a new path prefix in test_gufi.py for now

Looks good to me:
