title: NodeJS accessing file with relative path
body: <p>It seemed like a straight forward problem. But I amn't able to crack this.
  Within helper1.js I would like to access foobar.json (from <code>config/dev/</code>)</p>
  
  <pre><code>root
    -config
     --dev
      ---foobar.json
    -helpers
     --helper1.js
  </code></pre>
  
  <p>I couldn't get this to work <a href="https://stackoverflow.com/questions/7083045/fs-how-do-i-locate-a-parent-folder">fs: how do I locate a parent folder?</a> </p>
  
  <p>Any help here would be great.</p>
