3. Only users may be a member of a group (no groups within groups).
4. Groups will have an internal UID that is associated with the group name to ensure group uniqueness (allowing non-unique group names).
5. Groups will be tracked in a database table where a 0 to many users to one group relationship may exist.
6. A group table entry will also hold the UID of the owner.
