   *     testing

   * DEFAULT CONTROLLER

   * 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.
   *
   * Un-comment the $routing array below to use this feature

   *  CUSTOM CONFIG VALUES

   * The $assign_to_config array below will be passed dynamically to the
   * config class when initialized. This allows you to set custom config
   * items or override any default config values found in the config.php file.
   * This can be handy as it permits you to share one application between
   * multiple front controller files, with each file containing different
   * config values.
