title: How to serve a static folder in sails.js?
body: <p>I want to serve a folder <code>app</code>, which is at the same level with <code>assets</code> folder, under the url <code>/app</code>. </p>
  
  <p>It's possible with <code>AppController</code> to serve file according the url, but I want to know whether it is possible to do this like the following with express?</p>
  
  <pre><code>app.use(express.static(__dirname + '/public'));
  </code></pre>
