Program: ComboTween
Version: 0.5
Author : Petit Publications http://petitpub.com
Usage  : This Actionscript 2.0 should be included in the first frame of the *.fla file
	 to run the show.
Purpose: To test the Tween class in tweening the scale and transparency of a JPG image.

// create a movieclip to load the photo into
