title: codeigniter class name convention
body: <p>When I'm developing in NetBeans I have a lot of confusion due to the amount of tabs open. In most cases the controller has the same name of the view or model.
  In the <a href="http://ellislab.com/codeigniter/user-guide/general/styleguide.html" rel="nofollow">convention style guide</a> they say that you can prefix a controller file name with a custom suffix, but doesn't work.
  My question is, there is any chance to end all the controller files with "_controller"?
  In my example the class is <code>class Verify_login extends CI_Controller {</code> and the file is named <code>verify_login.php</code>. Tried with <code>controller.verify_login.php</code> like they say in the guideline but as I say, doesn't work. Lots of confusion in codeigniter's documentation.</p>
