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.
Also verified that the "open" counts in the dashboard for the group

was updated correctly after creating an auto-assigned review request.
