Examples of TupleList

mondrian.calc.TupleList
List of tuples.
Design notes
- Consider changing {@link TupleCalc#evaluateTuple(mondrian.olap.Evaluator)}and {@link mondrian.olap.Evaluator.NamedSetEvaluator#currentTuple()}to List<Member>
- Search for potential uses of {@link TupleList#get(int,int)}
- Worth creating {@link TupleList}.addAll(TupleIterator)?
