C01

This completes the c01 in-class exercise.

The purpose of this exercise is to show the students some of the power of what they can do with jQuery.

The instructor should walk through the example, or code it from scratch. 

I think the proper thing to do would be to have the instructor *walk* through this example in class, because there are quite a few moving parts, and the opportunity for an instructor to make a mistake and get stuck would likely be high. But, because there are tons of comments, the code is self-documented, and the instructor would merely have to give higher level explanations.

A ton of the actual exercise, as specified in the README file is not completed, on purpose. The idea is to assign a lot of that later in the class as homework.
