-| 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.

-|
-|	http://codeigniter.com/user_guide/general/routing.html
-|
-| -------------------------------------------------------------------------
-| RESERVED ROUTES
-| -------------------------------------------------------------------------
-|
-| There area two 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 what URI segments to use if those provided
-| in the URL cannot be matched to a valid route.
