/**
* ## Sortable Extension
*
* Uses jQuery UI's sortable plugin to realize sortable functionality. You can pass sortable options via
* data attributes.
*
* ### Options
*
* **URL | data-sortable-handle | String | Optional**
*
* The destination URL to be used after the user clicks on the element.
*
* ### Example
*
* ```html
* <div data-gx-extension="sortable" data-sortable-handle=".drag-handle">
* <img src="handle.jpg" class="drag-handle" />
* </div>
* ```
*
* This extension is based in the jQuery UI sortable interaction utility:
* {@link http://api.jqueryui.com/sortable}
*
* @module Admin/Extensions/sortable
* @requires jQueryUI
