/**
* A PermissionRole represents a collection of permission codes that can be applied to groups.
*
* Because permission codes are very granular, this lets website administrators create more
* business-oriented units of access control - Roles - and assign those to groups.
*
* If the <b>OnlyAdminCanApply</b> property is set to TRUE, the role can only be assigned
* to new groups by a user with ADMIN privileges. This is a simple way to prevent users
* with access to {@link SecurityAdmin} (but no ADMIN privileges) to get themselves ADMIN access
* (which might be implied by certain roles).
*
* @package framework
* @subpackage security
*
* @property string Title
* @property string OnlyAdminCanApply
*
* @method HasManyList Codes() List of PermissionRoleCode objects
* @method ManyManyList Groups() List of Group objects
