Remaining HW (plus others..)

I don't know what happened here, but things blew up again when I tried to start a new branch to submit HW7 in the same way I submitted HWs 4 and 6. Git wanted to upload every file in the ASTR599_homeworks directory again, so I had to delete everything but my homeworks, start a new branch, delete the entire log, and add and commit my homework to get it to work. I'll try to submit my last homeworks to this branch. I think this brings me to 5/6.
