Altered the access part of the model to include a new user type
(Superuser).  This is to allow the Administrative user type to add
patients but not have destructive access to anything.  The Superuser is
intended to be a technical administrator or developer.  The
Administrative user is intended to be a charge nurse or someone in the
PICU to whom user-creation has been delegated.  Normal users cannot
create users or access the databases, etc.

I have also added the plugins that are generated by EMF.
