Business-day arithmetic with a caller-supplied calendar: add or subtract N working days from a date, or count the working days between two dates. The weekend is specified as a weekday mask so Friday-Saturday and Sunday-only weeks work, and holidays are passed in as an explicit date list, so the answer never depends on a holiday table that can go stale. Returns the result date, the day count, and the first 1,000 skipped dates with the reason each was skipped.
