dbd2() is a Days between Dates program that beats the calculator
at its own game! Whereas the calculator can only find the number
of days between dates ranging from 1950 to 2049, this program can
find the number between ANY DATE (-inf to +inf). It still uses
the Gregorian Calendar, and its still just as fast!
