> I took advantage of some of the new reflection features in Scala 2.10 to make automatic serialization of case classes much cooler, viz.,
> 1) We can automatically map any case class to a TupleN and properly infer PTypes for Scala types (options, lists, etc.), just as we do for regular PCollections.
> 2) For Avro serialization, we will also capture the names of the case class' fields and map them to the names of the fields in the Avro record we generate, which makes debugging intermediate outputs much easier.
