Week 5 - A bit late

As mentioned, this update is slightly behind schedule thanks to a preoccupation with the Tour of HanoiAnne Hoy assignment. While not complete yet, this assignment has been the object of particular annoyance for the past week or more, and I have not yet even worked on the recursion part, which will probably actually be easier, interestingly. One positive product of this however is that I finally decided to make use of doctest, and to good effect. On the other hand, I really wish instructors gave better descriptions on how to use code that's provided. I spent about an hour messing around with the GUIController and trying to debug my own code, not realizing that I was supposed to click on the "stool" rather than the space above it in the interface.
