Started working on displaying courses

I have now created the models in the database, for creating courses in the admin area, and display them in the company section. I added a department in between the university model and student model. This caused quite a lot of problems, and I could not figure out how to migrate the sections. In the end, I simply deleted the database locally and created it again.. I really need to figure out how to migrate data properly, since I could never do such a thing when the website is live.
