This Thursday, by the time you get to lab.

0. Send your TA your GitHub user name. Do this IMMEDIATELY
1. Clone this repo
2. Answer the questions in "questions.md" in a NEW BRANCH. When showing code, your answers should be correctly formatted using Markdown!
3. Submit a pull request based on your changes
4. Request a code review from your TA

You will probably have to do Google searches, etc., to figure out some of the answers. That's part of the job when doing computational work--you have to figure things out.
