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!
OK as I get further I see I was wrong about what bedtools does! But I'd like a description of aims upfront i.e. this lesson will show you how to  do x,y,z in order to perform task A. This pipeline can be used to answer biological questions such as ... whatever the example data is for.
