This Source writes out the TupleEntry as a simple JSON object, using the field names as keys and the string representation of the values.

TODO: at the next binary incompatible version remove the AbstractFunction2/scala.

object TypedJson extends Serializable

This type uses the structural type of a case class, but not it's name, to describe the Json using json4s.
