MergePreferred

class MergePreferred[T] extends Graph[MergePreferredShape[T], Unit]

Merge several streams, taking elements as they arrive from input streams (picking from preferred when several have elements ready).

A MergePreferred has one out port, one preferred input port and 0 or more secondary in ports.

Emits when one of the inputs has an element available, preferring a specified input if multiple have elements available

Backpressures when downstream backpressures

Completes when all upstreams complete

Cancels when downstream cancels

A Broadcast has one in port and 2 or more out ports.
