Bioinformatics python capstone lesson

This lesson is intended to be a 1.5 hour demo that will sit at the end of a novice python bootcamp and show learners how to apply some of their new skills to bioinformatics. Currently work in progress, contributions/suggestions very welcome!
Ah, nice! Here is the biological question I was looking for up front! I think it is worth repeating - keeping this here but also introducing the Q. in the intro.
