[Tweener] scrollbar API and tweener

[Zeh Fernando]

Well, first you have to figure how to create and use the scrollbar with no
tweening engine whatsoever -- they may have examples of that in their
documentation. Then you can proceed to the stage of tweening the value.

It seems that after you've created a ScrollManager, you can set the scroll
property with:

     scrollManager.setCurrentPosition();

This means it's not something you can directly tween. You need to create a
property for that -- then either updating the value onUpdate, or with a
getter/setter for that. In the latter, it'd look something like this added
to your class:

     protected var _scrollPos:Number;

     public function get scrollPos(): Number {
         return _scrollPos;
     }

     public function set scrollPos(__value:Number): void {
         _scrollPos = __value;
         scrollManager.setCurrentPosition(__value);
     }

Then you can tween it with:

     Tweener.addTween(this, {scrollPos:10, time:1});

Or use any other random tweening extension in the same way.
