Customize controller for a route

[RETFU]

The controller is determine by convention:

/item/{itemId}/ -> Item
/item/{itemId}/comment -> Item\Comment

But sometime you need to choose the controller manually

API proposal

<?php
$rrest = new RREST\RREST($apiSpec, $router, 'XXX\Controllers');
$rest->addControllerAlias('/item/{itemId}/comment', YYY\ZZZ\Comment);
$rest->addControllerAlias('/item/{itemId}/ping', YYY\ZZZ\Ping);
$rest->removeControllerAlias('/item/{itemId}/ping');
