novice submodule

Following Greg Wilson's [blog post](http://software-carpentry.org/blog/2012/11/who-wants-to-write-a-little-code.html) on Software Carpentry, here's code for a "novice" submodule. This is meant for beginners who are taking a class like George Tech's [Media Computation](http://coweb.cc.gatech.edu/mediaComp-teach).

See the README and example.py for details.
