def permitted_to! (privilege, object_or_sym = nil, options = {})
      authorization_engine.permit!(privilege, options_for_permit(object_or_sym, options, true))
    end
def permitted_to! (privilege, object_or_sym = nil, options = {})
      authorization_engine.permit!(privilege, options_for_permit(object_or_sym, options, true))
    end
Works similar to the permitted_to? method, but
 throws the authorization exceptions, just like Engine#permit!
