-:[ script history ]:-
04.15.2001 .
07.09.2001 Updated script so that count down was possible for an event in a
different year.

____
-:[ script summary ]:-
Count down to a special event with this script. Enter the date in MM.DD.YYYY
format when instantiating the class and call the displayCountdown method
wherever you want the countdown to be displayed.
It is recommended that you include this file in another PHP document and create
an instance to the countdown class in there. This can be done by doing
something similar to this:
include( "directory/to/this/file/countdown.php" );
$count = new countdown( "11.06.2001" );
echo $count->displayCountdown() . " days until my birthday.";

IT works but it has on problem. If the event has passed the num_days_left is not = 0. In other words the script it not capable of producing a negative value.
