The package "methods" exports an array of HTTP methods, including a bunch of esoteric ones. But, unless I'm missing something, it doesn't seem to be needed-- this line iterates over the methods array, but is only actionable if it matches a key in `req.app.routes`.

Would it be better to just iterate over `Object.keys(req.app.routes)`? That'd generally be just `['get', 'post']` for web apps
