- *
- * Added Awesomeness: Phil Sturgeon
- *
- * Location: http://github.com/benedmunds/CodeIgniter-Ion-Auth
- *
- * Created: 10.01.2009

- * Description: Modified auth system based on redux_auth with extensive customization. This is basically what Redux Auth 2 should be.
- * Original Author name has been kept but that does not mean that the method has not been modified.
- *
- * Requirements: PHP5 or above
