Akka-reactive-streams ByteString comparator junction for arbitary number of inputs. Emits stream of boolean true until first mismatch occured/main input terminated, then emits single false value and terminates.

	import akka.util.ByteString
	import akka.stream._
	import FanInShape.Name
	import FanInShape.Init


	class BinaryComparatorPorts(n: Int, _init: Init[Boolean] = Name("BinaryComparator")) extends UniformFanInShape[ByteString, Boolean](n, _init) {
	// comparison target; other ports are used for possible duplicates
	val src = newInlet[ByteString]("src")
	protected override def construct(init: Init[Boolean]) = new BinaryComparatorPorts(n, init)
