+$app = new Cors($app, array(
+    // you can use array('*') to allow any headers
+    'allowedHeaders'      => array('x-allowed-header', 'x-other-allowed-header'),
+    // you can use array('*') to allow any methods
+    'allowedMethods'      => array('DELETE', 'GET', 'POST', 'PUT'),
+    // you can use array('*') to allow requests from any origin
+    'allowedOrigins'      => array('localhost'),

+$cors->addActualRequestHeaders(Response $response, $origin);
+$cors->handlePreflightRequest(Request $request);
+$cors->isActualRequestAllowed(Request $request);
+$cors->isCorsRequest(Request $request);
