I've been using nb_black lately and it's wonderful. https://github.com/dnanhkhoa/nb_black

We can add this with %load_ext lab_black for our notebook examples and it will auto-format every cell to fit black to make it more clean and readable without us having to worry about it.

The instructions and configurations listed in hn2016_falwa/examples/ to run the sample codes are specific to conda users. It would be great to include instructions for pip/virtualenv users as well, as many scientists are actually using that.
