title: Reflection for nested classes
body: <p>I see that most people who have been playing with ScalaSigParser, in an effort to ser/des idiomatic Scala case classes in a nice way, have avoided this issue, but I'd like to know if it's possible.  I have a situation much like the following:</p>
  
  <pre><code>trait OuterTrait {
    abstract class InnerAbstract(i: Int)
  }
  
  object OuterObject extends OuterTrait {
    case class InnerConcrete(i: Int) extends InnerAbstract(i)
  }
  
  val bippy = OuterObject.InnerConcrete(123)
  
  val s = serialize(bippy)
  
  // time passes...
  
  val obj = deserialize[OuterObject.InnerConcrete](s)
  </code></pre>
  
  <p>So, I can find the ScalaSig for OuterTrait, but I haven't managed to find a nice general way to identify the outer object from the InnerConcrete class.  Any protips?  </p>
