Paper: Frequentism and Bayesianism: A Python-driven Primer (Jake VanderPlas)

This is the final version – ready to be reviewed.
@jakevdp - I assure you this comment was not coming from an emotional frequentist reponse on my part, I, in most situations tend towards a Bayesian approach.  

I simply meant here that I think the footnote seems odd as a footnote because of how detailed it is, given that similar content in the other section was actually in-text.  Personally, I would be fine with either dramatically shortening the footnote to just say something like "there is a better frequentist way [citation], but the intent here is to be illustrative", or move the footnote into the text.  My complaint was not so much about wether this should be addressed but rather the fact that what seems to be a substantial amount of content is in a footnote.
