Db dev -- please review and let's move forward..

Hey Dave,
Please take a look at code and let me know if we should reorganize stuff.
load_FCS.py should push all in folder to the database, although I have not done any extensive checking...

- We should add tests next (while ideas our fresh) --  I will add a framework for this and first test
- Lets merge this to master together tomorrow or whenever
- Like you said, after we address this merge and build tests, I think your time would be best spent pushing forward -- working on manipulation of FCS.dat (clean, de-correlate, normalize, ...)
- I will work on adding tests for db, db query functions, retrieval of fullpaths from, and importing HPdb/LIS data

Thanks!
-Dan
