[eluser]wiredesignz[/eluser]
This is the View Library (application/libraries/View.php) it is autoloaded at startup.

Code:

<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* View Library
*
* Useage:
* 1: Renders a layout with partials (blocks) inside.
* 2: Renders partials only (header,content,footer. etc).
* 3. Allows a plugin to render a partial.
*
* Allows a view source directory to be specified.
