case classFanOut[T](targets: Seq[PhysicalNode[T]]) extends PhysicalNode[T] with Product with Serializable
This is a convenience that pushes each item it receieves a sequence of other
PhysicalNodes. This is so we don't have to deal with the notion of fan-out
on the summingbird graph (multiple consumers from a single node) in each type
of node.
