public class CalcNumberedStream1<In,E>
extends BaseNumberedStream1<In,E>

Make a stream that is using a Calc1 class to do a calculation, based on a named input stream stored in a context.
Based on ListCalcStream1.
Uses lazy setup so input stream does not have to exist when stream is created.
There should be a way to say whether you have to calculate all the values sequentially to use this.
Close to NamedListCalcStream1, but with no caching.
