Tweener, better?

Baby steps. I think there are more things I will need to see with this class before I am 100% sold. Anyone else using it?

//Import so we can use:
import caurina.transitions.Tweener;

//Let's make something move:
Tweener.addTween(box_mc, {_alpha:50, time:1, transition:"linear"});

Tweener.addTween(box2_mc, {_x:-10, time:1, delay:3, transition:"linear"});
