Render notebooks on a webpage

[jrbourbeau]

The notebook examples in https://github.com/dask/dask-examples are rendered with sphinx at https://examples.dask.org. My sense is it'd be nice to do the same thing here.

If I were to do this, I'd probably follow the prior art in dask-examples by running the sphinx quickstart command and then add nbsphinx (https://github.com/spatialaudio/nbsphinx/) to the sphinx-generated conf.py file. There may be some additional tweaking that's needed, but my guess is that gets us 80% of the way there.
