 This short view is intended to be called to handle short views for roles
 
 The following vars should be set by the jsp that is calling this short view 
 personToRolePredicate: URI of the person to role predicate.
 roleToPersonPredicate: URI of the role to person predicate. 
 roleActivityToRolePredicate: URI of the activity to role predicate.
 roleLabelForPerson: human readable label for person when viewing from non-person side of role. Most short views 
     don't specify this value because the role name is displayed instead. Grant-related short views specify
     this value because there is no specific role name. 
 roleActivityLabel: human readable label of activity used for error messages
