        This example builds on
        Instead of moving the actual html element that was clicked, we have a hidden
        layer, empty aside from a border, absolutely positioned, that we place in the same 
        location of the clicked object.  The onDrag event handler was implemented so
        that the style of the DragDrop elements change when they interact.  The onDragDrop
        event handler was implemented so that the elements swap positions if one is dropped
        on another.
