* Include the path if the folder is not in the same directory
* as this file.

*
* If you want this front controller to use a different "application"
* folder than the default one you can set its name here. The folder
* can also be renamed or relocated anywhere on your server. If
* you do, use a full server path. For more info please see the user guide:
* http://codeigniter.com/user_guide/general/managing_apps.html
