Adopt the continuous integration and html rendering of NASA-NAVO/navo-workshop

@bsipocz has implemented a very nice continuous integration and rendering into html in the [NASA-NAVO/navo-workshop](https://github.com/NASA-NAVO/navo-workshop) repository. The notebooks are [rendered](https://nasa-navo.github.io/navo-workshop) automatically, and CI is run periodically, not just when commits are made. We could adopt the same scheme here.

Start by comparing this repository with the CI and HTML-rendering setup in the linked NASA-NAVO/navo-workshop repository and its rendered site. Determine the corresponding configuration entry points here; done means the notebooks render automatically and CI runs periodically, not only after commits.
