 * Prepends or appends buttons to input fields.

 * For prepending/appending text see {@link InputGroupAddon}.
 * Needs to be encapsulated in an {@link InputGroup}.
 * <p/>
 * <strong>Note:</strong> This is not a button itself! A {@link Button} needs to be added to this container.
 * <h3>UiBinder example</h3>
