This example shows how to drag a Shape instance. When using <code>DD-Drag</code>, you normally assign an HTMLElement to the Drag's <code>node</code> attribute. Since Shape instances act as a normalization layer across browsers, you never directly interact with their
underlying Dom elements. This is true when using Drag as well. When creating a Drag, assign the Shape instance to the Drag's <code>node</code> attribute.
a shape.
