Development

- Changed router so it supports both string and object as exception handlers.
- Added `Router::error($callback)` method to `Router` class (issue #238).
- Fixed issues calling `getController` and `getMethod` when callback is an object (issue #239).
- Updated documentation to reflect new changes.
- Added `addExceptionHandler` to `IGroupRoute` interface and `RouteGroup` class.
- Other minor bugfixes and optimisations.

-# ExceptionHandler
+# ExceptionHandlers
 
 ExceptionHandler are classes that handles all exceptions. ExceptionsHandlers must implement the `IExceptionHandler` interface.
 
-## Example
+## Handling 404, 403 and other errors
 
-Resource controllers can implement the `IRestController` interface, but is not required.
+If you simply want to catch a 404 (page not found) etc. you can use the `Router::error($callback)` static helper method. 
+
+This will add a callback method which is fired whenever an error occurs on all routes.
+
+The basic example below simply redirect the page to `/not-found` if an `NotFoundHttpException` (404) occurred. 
+The code should be placed in the file that contains your routes.
+
+```php
+Router::get('/not-found', 'PageController@notFound');
+
+Router::error(function(Request $request, \Exception $exception) {
+    if($exception instanceof NotFoundHttpException && $exception->getCode == 404) {
+        response()->redirect('/not-found');
+    }
+});
+```
+
+## Using custom exception handlers
 
 This is a basic example of an ExceptionHandler implementation (please see "[Easily overwrite route about to be loaded](#easily-overwrite-route-about-to-be-loaded)" for examples on how to change callback).
