    | URI ROUTING
    | -------------------------------------------------------------------------
    | This file lets you re-map URI requests to specific controller functions.
    |
    | Typically there is a one-to-one relationship between a URL string
    | and its corresponding controller class/method. The segments in a
    | URL normally follow this pattern:
    |
    |	example.com/class/method/id/
    |
    | In some instances, however, you may want to remap this relationship
    | so that a different class/function is called than the one
    | corresponding to the URL.
    |
    | Please see the user guide for complete details:
    |

    | RESERVED ROUTES
    | -------------------------------------------------------------------------
    |
    | There are three reserved routes:
    |
    |	$route['default_controller'] = 'welcome';
    |
    | This route indicates which controller class should be loaded if the
    | URI contains no data. In the above example, the "welcome" class
    | would be loaded.
    |
    |	$route['404_override'] = 'errors/page_missing';
    |
    | This route will tell the Router which controller/method to use if those
    | provided in the URL cannot be matched to a valid route.
    |
    |	$route['translate_uri_dashes'] = FALSE;
    |
    | This is not exactly a route, but allows you to automatically route
    | controller and method names that contain dashes. '-' isn't a valid
    | class or method name character, so it requires translation.
    | When you set this option to TRUE, it will replace ALL dashes in the
    | controller and method URI segments.
    |
    | Examples:	my-controller/index	-> my_controller/index
    |		my-controller/my-method	-> my_controller/my_method
