Tim's Test

This is my ten tests for Homework 6. Some of the tests are failing and I do not know why. Might be an actual error.
http://msdn.microsoft.com/en-us/library/system.object.gethashcode(v=vs.110).aspx gethashcode is a defualt c# thing, not a part of the graph library. i don't know what it does when it has not been implemented, hence why it is giving weird bevavior. also, we probably dont need to test this, unless they explicitly implement it.
