* special instances where you might want to override the standard
* routing in a specific front controller that shares a common CI installation.
*
* IMPORTANT: If you set the routing here, NO OTHER controller will be
* callable. In essence, this preference limits your application to ONE
* specific controller. Leave the function name blank if you need
* to call functions dynamically via the URI.

* CUSTOM CONFIG VALUES

* This can be handy as it permits you to share one application between
