title: Loading Codeigniter library from a different folder under application folder
body: <p>Hi I am having an issue</p>
  
  <p>Say I have a folder structure in CodeIgniter</p>
  
  <pre><code>application/
      controllers/
      models/
      views/
      gmail_library/
  </code></pre>
  
  <p>Now I have written a controller</p>
  
  <pre><code>class invite_friends extends CI_Controller {
  
      function __construct() {
          parent::__construct();
          $this-&gt;load-&gt;gmail_library('Config'); // this line is giving me error
          session_start();
      }
  }
  </code></pre>
  
  <p>How can I set this thing like this?</p>
