Is there a suggested order to explore docs/notebooks/? Perhaps not...

[mccalluc]

https://github.com/vitessce/vitessce-python/blob/master/docs/widget_examples.rst determines the listing order for the notebooks in the generated documentation... but if there's a definite order a new user should look at these, should that be captured in the README.md? Or maybe the filenames could be numbered, so a jupyter user could just go down the list?

Somewhat related: How does the Jupyter user download the prerequisite data? #76

I think the numbering of the files is a good idea
