[Tweener] Using passing variables through event listeners totrigger correct tween

[Gerry Creighton]

Yeah you can do it different ways...I just wanted to show you how it's  
done in AS3 so that you don't create
'unnecessary code'.
The topic of passing arguments with eventListeners has come up in the  
past, Learning Actionscript 3.com
has a post on this very topic that you can read up on here:
http://www.learningactionscript3.com/2008/11/11/passing-arguments-with-events/

The code I passed along allows you to do what you want to do for  
rollOvers, rollOuts and the Move but
does not handle the CLICK. The click could be handled easily as well.
