Try changing to hugo

[QuLogic]

It's an idea I had when @joelostblom mentioned hugo's notebook integration. It'd be really nice to get lessons that used notebooks or R markdown more integrated with the site, instead of having a minimal lesson page with a link to the notebook.

This is not super easy to do with the builtin jekyll since GitHub doesn't have any support for plugins.

I haven't looked into the details but at least the theme is available and setting up Travis or some other CI is straightforward.

@linamnt was thinking this might be something to do on another (partly virtual) sprint day if we have one.
