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!
Throw in a reminder about what -ow flag means i.e. "Remember that the -wo (write overlap) option reports the number of base pairs of overlap between the features that overlap between each of the files."
