Admin can create Agency Admins & Agency Admins can edit details of their own agency

This will allow the super admin user to create users that act as admins for a specific agency.
The agency admins can then edit and review their agency's details. 
Just from the perspective of who is going to be an admin in this situation and how someone will become an "agency admin," it will be more of an assignment, like "I've created the agency and I'm giving you a 'log-in' to use to monitor your details." I see it less as being a specific person and more of a general access point for an agency. not sure if that made any sense.
