*
* 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'
* });
* </code></pre>
