This function helps further abstract agents.  We want to get all users
belonging to a pad that is owned by a group, or more specifically - an
agent.  If this agent is a user, that user is our only user to collect.
If this agent is a group, we want to capture _it's_ owner along with all
of it's members.

Setup to perform an iteration of development focused on a simpler
implementation and eliminating redundancy in design.

This function will initialize a new group object and write it to the
database, with a given group name and owner user.
