Week 7

Week 7 went pretty much like week 6. I went to one of the researchers here. He looked at my code and could not find anything wrong. He suggested that I convert my wall list to sets instead of vectors. I did that, ran into a few problems and learned that sets have to know that my wall will not change, so I had to alter some of my code and declare them constants. After all that, I still ran into the same problem. Sometimes I code ran and other times, I would only add a few walls and then stop.
