+ * --------------------------------------------------------------------
+ *
+ * Normally you will set your default controller in the routes.php file.
+ * You can, however, force a custom routing by hard-coding a 
+ * specific controller class/function here.  For most applications, you
+ * WILL NOT set your routing here, but it's an option for those 
+ * 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.
