Refs: 18F/foia-hub#84
- Updating usagov script to only handle data pull only.
- Updating data in the repo w/ a fresh pull.
- Created sample data set from the full set. Adding it to the repo. 
I think that, if an exception is thrown, `data` won't be instatiated, so the interpreter will explode a few lines down.
