jQuery Auto Positioning: Move elements to stay within a specified boundary

This is a jQuery plug-in that can move page elements to stay within a specified boundary.

It can animate a page element to move or resize so it stays with the boundaries of the parent element, another page element or the page screen.

The plug-in can animate the target element with automatic speed, so it does not take more than a given time limit to reach the final position and size.

The final position and size may consider a given margin around the target element relatively to the container elements.

Given callback functions may be called before and after the positioning animation happens.
