The Date class is a general date data type(Object) that is similar to those built in to other languages. It supports all days from January 1st, 1000 D.C. through December 31st, 2999. It checks to make sure that the dates that are instanciated or changed exist and if they don't an exception is thrown. It provides methods to advance the date backwards and forwards by increments of day, week, and month. It provides comparisons =,>,<. Added by Allan C. Solomon and modified by guich.
