Concrete date class.
This class provides methods to inspect dates as well as methods and operators which implement a limited date algebra (increasing and decreasing dates, and calculating their difference).
next given weekday following or equal to the given date
E.g., the Friday following Tuesday, January 15th, 2002 was January 18th, 2002.
n-th given weekday in the given month and year
E.g., the 4th Thursday of March, 1998 was March 26th, 1998.
