Mason's statistics labs

These are the labs that Mason wrote before he left. Abraham was wise enough to have me get a copy of them before the OS was updated on the mac in the lab. We need to go through them, figure out which of the files I have added are actually needed for the labs and eliminate the others. It also appears that each lab was made to compile individually, so we will have to make a volume 3 file and reformat the labs so that they compile there. DO NOT MERGE THIS RIGHT NOW. I am opening the pull request because I am going to need input on this one.
