Added the files for the fourth homework assignment

So I didn't get to spend as much time working this weekend as I had hoped. I would like to use this assignment as a starting point to create an actual portfolio site for myself. Over the next couple of days I think I will overhaul this code greatly (especially after all the material we covered in class today). I still have a lot to learn and try out, so I will keep at it. I expect there to be a lot more to these pages for the next assignment. Thanks!
