BigDate 4.6 -- replacement for Java Date class.
Handles dates 999,999 BC to 999,999 AD, the
missing year 0, the missing 10 days in 1582, and
the switch to the 100/400 leap year rule in 1600.
Heavily commented Java source included.  Copyright
1997-1999 Canadian Mind Products.  Supports ISO
WeekNumbers and ISO Day of week.  If you want do
do calculations on pure dates, ignoring timezones
and time, BigDate is much easier and faster than
the Sun Date and Calendar classes.  See TestDate
for sample uses.
