Pair programming

Related to #10:

In the past, we've done some "pair programming" assignments. These have met with mild success, and got the students talking to each other. In the days of Processing OOP, I used to have them exchange classes. You can see some relics here:

See assignments week 2, 3, and 5.

If anyone has any ideas on how to improve this or whether or not to do this, let's discuss.
