can_handle()
                
                can_handle(\midcom_db_topic  $current_object, \Symfony\Component\HttpFoundation\Request  $request, integer  $contextid) : boolean
                Relays the can_handle call to the component, instantiating a new site
class. It will execute can_handle of that class, returning its result
to MidCOM.
