EventDispatcher Component
=========================

The Symfony2 EventDispatcher component implements the Mediator pattern in a
simple and effective way to make your projects truly extensible.

```php
use Symfony\Component\EventDispatcher\EventDispatcher;
use Symfony\Component\EventDispatcher\Event;

$dispatcher = new EventDispatcher();

$dispatcher->addListener('event_name', function (Event $event) {
    // ...
});

$dispatcher->dispatch('event_name');
```
