Looks cool, but I don't really have time to deal with powerschool's spaghetti code (especially their html!) at the moment. I'm currently planning on implementing some main features so this would be less priority for me.

If you have time, feel free to submit a PR! I'll check it out :)
I haven't really documented my code that much though but if you're interested in helping out I'll start some of that.
