Producer2FlatMapOperation

object Producer2FlatMapOperation

A utility for converting a series of producers into a single FlatMapOperation This simply folds through a list of producers converting them into an operation from T => Future[TraversableOnce[U]]. This allows us to combine simple map, flatmap with also left joins.

This is platform specific, as the contents of what are in Producer's are also platform specific.
