title: cocos2d subclassing sprite to handle touch?
body: <p>I'm new to the cocos2d(-x) world.  </p>
  
  <p>I'd like to detect a touch to a sprite, and tutorials/examples seem to suggest using layer to detect touch and find the approapriate  sprite with bounding box.  </p>
  
  <p>Is subclassing sprite to allow touch detection generally a bad idea?  </p>
