title: Ignoring a property during deserialization
body: <p>I have a class that is serializing very nicely - finally!</p>
  
  <p>Now I want to add a property to this class, that I don't want to be serialized at all. </p>
  
  <p>Is it possible to add this new property with some kind of attribute so that when I call serialize or deserialize methods, this property will go unnoticed?</p>
