Create a tutorial with an example project with notebooks

[willingc]

The README.md has a nice example. It would be helpful to provide that example to the user.

I think there are (at least) 2 ways we can address this:

1. the readme provides code that can create a mock directory and files that the user can explore on their own
2. we create a separate repository/template that links into the readme that already contains a data/ and analysis/ folder with notebook files in the root and analysis/ folder for people to download and explore on their own
   • We could maybe even set that example repo as a binder instance?
3. Some combination of the above where we put everything in this repo's examples/ directory
