+/**
+ * @class Roo.dd.DragDrop
+ * @extends Roo.util.Observable
+ * Defines the interface and base operation of items that that can be
+ * dragged or can be drop targets. It was designed to be extended, overriding
+ * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
+ * Up to three html elements can be associated with a DragDrop instance:
+ * <ul>
+ * <li>linked element: the element that is passed into the constructor.
+ * This is the element which defines the boundaries for interaction with
+ * other DragDrop objects.</li>
+ * <li>handle element(s): The drag operation only occurs if the element that
+ * was clicked matches a handle element. By default this is the linked
+ * element, but there are times that you will want only a portion of the
+ * linked element to initiate the drag operation, and the setHandleElId()
+ * method provides a way to define this.</li>
+ * <li>drag element: this represents the element that would be moved along
+ * with the cursor during a drag operation. By default, this is the linked
+ * element itself as in {@link Roo.dd.DD}. setDragElId() lets you define
+ * a separate element that would be moved, as in {@link Roo.dd.DDProxy}.
+ * </li>
+ * </ul>
+ * This class should not be instantiated until the onload event to ensure that
+ * the associated elements are available.
+ * The following would define a DragDrop obj that would interact with any
+ * other DragDrop obj in the "group1" group:
+ * <pre>
+ * dd = new Roo.dd.DragDrop("div1", "group1");
+ * </pre>
+ * Since none of the event handlers have been implemented, nothing would
+ * actually happen if you were to run the code above. Normally you would
+ * override this class or one of the default implementations, but you can
+ * also override the methods you want on an instance of the class...
+ * <pre>
+ * dd.onDragDrop = function(e, id) {
+ * alert("dd was dropped on " + id);
