add sample code and data for peer review excercise

so you leave this workshop and go back to your lab, and excited tell your lab
partner about all the cool things you learned. you lend a copy of your notes
and your partner comes back in about a week saying "I made a thing!"

With a little additional research, your partner managed to adapt your notes
to a data set you have been working on. They would like you to review their
program and give them feedback -- what did they do well? what could they do
better? How would you change the program?
