\brief The QRomanCalendar class is a shared base for calendars based on the
ancient Roman calendar.
\section1
Calendars based on the ancient Roman calendar share the names of months,
whose lengths depend in a common way on whether the year is a leap
year. They differ in how they determine which years are leap years.
