All listener methods must be defined here otherwise PHP throws fatal error.
The third way of creating a listener is a very elegant one. You can make a class that
implements Doctrine_Overloadable. This interface has only one method: __call(),
which can be used for catching *all* the events.
class MyDebugger implements Doctrine_Overloadable
{
public function __call($methodName, $args)
{
echo $methodName . ' called !';
}
}

Attaching listeners
You can attach the listeners to a connection with setListener().
$conn->setListener(new MyDebugger());

If you need to use multiple listeners you can use addListener().
$conn->addListener(new MyDebugger());
$conn->addListener(new MyLogger());

Pre and Post Connect
All of the below listeners are invoked in the Doctrine_Connection class. And they are all
passed an instance of Doctrine_Event.
