A simple extension for auto-assigning students working on Review Board to

the "students" group.
I can imagine this maybe being useful for other projects as well, so I can

see this expanding out to allow multiple auto-assignments, but for now I've

just hard-coded the "students" group.

Created some test users and a "students" group. Entered the extension

configuration page and added some users in the comma-separated list to

auto-assign. Created review requests for the users in the list and saw

that they were correctly added to the "students" group. The review requests

from the other users were not.
