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!

here.  But if you do use the link name <link address> form you need backticks rather than quotes otherwise it doesn't render correctly.
