   *
   * A base class for Resize, providing:
   * <ul>
   *    <li>Basic Lifecycle (initializer, renderUI, bindUI, syncUI, destructor)</li>
   *    <li>Applies drag handles to an element to make it resizable</li>
   *    <li>Here is the list of valid resize handles:
   *        <code>[ 't', 'tr', 'r', 'br', 'b', 'bl', 'l', 'tl' ]</code>. You can
   *        read this list as top, top-right, right, bottom-right, bottom,
   *        bottom-left, left, top-left.</li>
   *    <li>The drag handles are inserted into the element and positioned
   *        absolute. Some elements, such as a textarea or image, don't support
   *        children. To overcome that, set wrap:true in your config and the
   *        element willbe wrapped for you automatically.</li>
   * </ul>
   *
   * Quick Example:
   *
   * <pre><code>var instance = new A.Resize({
   *  node: '#resize1',
   *  proxy: true,
   *  preserveRatio: true,
   *  wrap: true,
   *  maxHeight: 170,
   *  maxWidth: 400,
   *  handles: 't, tr, r, br, b, bl, l, tl'
