## routing part.
$app->addRoute(Array(
  "route1"=>Array(
      "method"=>"get",
      "uri"=>"test",
      "execute"=>function($result)
        {
          ## forward to other route.
          return $app->execute('route2',Array('my-param'=>'this is value from route1'));
        }
      }
    ),
  "route2"=>Array(
    "method"=>"get",
    "uri"   =>"hello/[:my-param]",
    "execute"=>function($result)
      {
        return "you're here. ".$result->params['my-param'];
      }
  )
))

## mock the uri.
echo $myapp->execute(Array(
  "method"=>"get",
  "uri"=>"test"
));
