    'bind:execute'=>function($param,$execution)
        {
          // do authentication or anything here.
          
          // do main execution on behalf of the framework. (you may pass parameter if you want.)
          return $execution($param);

  'sent'=>Array('get','sent',function(){ }),
  'view'=>Array('get','view/[:id]',function(){ })
              );

$app->map->addRoute('pm',$routes);
