Gitting around

Due 2020-09-22.

1. Create a Github account for yourself if you do not already have one.
2. Fork the demos repository from the class Github under your account. Your fork should be private.
3. Give me read permissions to that repository (my Github ID is dbindel).
4. Run the centroid example (on your local machine or on Google Cloud Shell). Save the results to a file baserun.txt in the same directory, and add that file to your local copy.
5. Commit the new file and push to your repository on Github.
6. Submit the URL for your Github repository via CMS.
