class ZipWithN[A, O](zipper: (Seq[A]) => O)(n: Int) extends GraphStage[UniformFanInShape[A, O]]

Combine the elements of multiple streams into a stream of sequences using a combiner function.

A ZipWithN has a n input ports and one out port

'''Emits when''' all of the inputs has an element available

'''Backpressures when''' downstream backpressures

'''Completes when''' any upstream completes

'''Cancels when''' downstream cancels

Add the given attributes to this Graph. If the specific attribute was already present on this graph this means the added attribute will be more specific than the existing one. If this Source is a composite of multiple graphs, new attributes on the composite will be less specific than attributes set directly on the individual graphs of the composite.
