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!
Maybe add in a quick definition of bootstrapping? It can be kind of a buzzword, so it is fun for folks to know they are doing it!
e.g. "We are able to bootstrap our results by randomizing our actual data to generate a null distribution  of CpG islands across chromosomal locations. We can use this distribution to estimate how likely we would be to get these this extent of overlap by chance"
