| 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:
|
| 	www.your-site.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:
|
|	http://www.codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are 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['scaffolding_trigger'] = 'scaffolding';
|
| This route lets you set a "secret" word that will trigger the 
| scaffolding feature for added security. Note: Scaffolding must be 
| enabled in the controller in which you intend to use it.
|
*/

$route['default_controller'] = "welcome";
$route['scaffolding_trigger'] = "";
