Paper: Scientific Computing with SciPy for Undergraduate Physics Majors (Bill Baxter)

Paper for SciPy2014 proceedings.  I'm a GitHub and rst novice so this should be interesting!  I'm having two issues: first, I don't see how to get my figure file onto GitHub.  Second, I'm clearly doing the reference labels for tables and figures incorrectly.  Hopefully someone can point me in the right direction!
