Using Part 1 of Problem Set 1, you are asked to comment and improve on a colleague's work. The person you will choose is determined by your order in the pulldown menu of the main page. For example, Ben should comment on Bruce, Bruce on Nick, and all the way down to Hoeteck commenting on Ben (wrapped around). We don't have a form mechanism setup, so for now just put it inside your DBN buffer as a comment, and include a modified version of your colleague's program that reflects your suggestions.
