Add a method to add URos/declining.

It might be worth looking into a way to add URos/declining. Currently you can check the balance of these accounts and pay tuition, but there doesn't seem to be a way to add URos/declining.

We should probably deal with #30 first.

I agree, but I was thinking more long-term.
