title: Customizing existing Module
body: <p>I have a collection of helper functions and i like to merge them together with already existing utility modules.</p>
  
  <p>Somehow like this:</p>
  
  <pre><code>var customUtil = require('customUtilites');
  customUtil.anotherCustomFunction = function() { ... };
  
  exports = customUtil;
  </code></pre>
  
  <p>Can this be achieved somehow?</p>
