This class allows you to embed anchors into your application much like in HTML. It allows you to anchor to a dynamic point or UIComponent within a container. Since you construct the anchor manager you can dynamically create managers for many different containers across the application. You can also pass in whether to animate the scrolling, where to anchor (nearest edge, top, middle, or bottom), duration, and the easing algorithm to use. You can also add events to the anchorManager that will tell you when it is scrolling, and when the scrolling has finished.
The example I've posted HERE shows all of these features, try to click on the button that you're anchored to to dynamically move it around. The manager will know this and anchor to the new position the next time.
I've also posted the source and the sample application HERE.
