Add the code that we worked on on Tuesday

Hey man, this is a pull request! Basically what it means is that I've uploaded my changes to the code to my own version of your repository, and now I'm asking if you want to accept those changes and include them in your version of the repository. You can easily look over the files that I've changed below, and see if you think that including the changes would be useful. 

Since the repository is empty at the moment, this might be a good way to populate it with the code so you can work on it once you have git set up on Windows. Alternatively, if you've made a bunch of changes on your local machine and you'd rather push those up here first, you can wait and we can take a look at it next week!
