no, it was just for illustration....  roles are full string names...
'god' 'administrator' 'manager', 'owner', 'customer'
Initially I thought using an additional integer field as a 'priority'
'god' priority > 'administrator' priority >  etc....

the objective is presenting a collection for select option depending 
upon the current_user role
if 'god' then all collection (he can CRUD any role)
if 'admin' then all collection - 'god' and 'admin'
.....
