 * this can be translated into {@link BlankEval} but there are some notable exceptions.  Functions
 * COUNT and COUNTA <em>do</em> count their missing args.  Note - the differences between
 * {@link MissingArgEval} and {@link BlankEval} have not been investigated fully, so the POI
 * evaluator may need to be updated to account for these as they are found.
