Still getting the hang of Git

Between CrashPlan and Time Machine, and having never worked on a large,
collaborative project, I really haven't had to use version control all that
much.  This commit actually contains a stylistic overhaul to blast2bsrGraph.py.
The last one just contained the test files I've been generating.
