User, Group and Membership associations and partials for Group partials

The group partials (app/views/groups/_group_table.html.erb) and (app/views/groups/_group_table_row.html.erb) and group index pages still include puts statements used to debug which should probably be removed. At the very least the updated models with the associations you created last week should be made available. I don't remember if we updated or changed anything else.
