+ * It can be used to build a big heiracy, with parent etc.
+ * or you can just use this to render a single compoent to a dom element
+ * MYPART.render(Roo.Element | String(id) | dom_element )
+ *
+ *
+ * Usage patterns.
+ *
+ * Classic Roo
+ *
+ * Roo is designed primarily as a single page application, so the UI build for a standard interface will
+ * expect a single 'TOP' level module normally indicated by the 'parent' of the XComponent definition being defined as false.
+ *
+ * Each sub module is expected to have a parent pointing to the class name of it's parent module.
+ *
+ * When the top level is false, a 'Roo.BorderLayout' is created and the element is flagged as 'topModule'
+ * - if mulitple topModules exist, the last one is defined as the top module.
+ *
+ * Embeded Roo
+ * 
+ * When the top level or multiple modules are to embedded into a existing HTML page,
+ * the parent element can container '#id' of the element where the module will be drawn.
+ *
+ * Bootstrap Roo
+ *
+ * Unlike classic Roo, the bootstrap tends not to be used as a single page.
+ * it relies more on a include mechanism, where sub modules are included into an outer page.
+ * This is normally managed by the builder tools using Roo.apply( options, Included.Sub.Module )
+ * 
+ * Bootstrap Roo Included elements
+ *
+ * Our builder application needs the ability to preview these sub compoennts. They will normally have parent=false set,
+ * hence confusing the component builder as it thinks there are multiple top level elements. 
+ *
+ * String Over-ride & Translations
+ *
+ * Our builder application writes all the strings as _strings and _named_strings. This is to enable the translation of elements,
+ * and also the 'overlaying of string values - needed when different versions of the same application with different text content
+ * are needed. @see Roo.XComponent.overlayString

+ * @class Roo.dd.DragDrop
+ * @extends Roo.util.Observable
+ * Defines the interface and base operation of items that that can be
+ * dragged or can be drop targets.  It was designed to be extended, overriding
+ * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
+ * Up to three html elements can be associated with a DragDrop instance:
+ * <ul>
+ * <li>linked element: the element that is passed into the constructor.
+ * This is the element which defines the boundaries for interaction with
+ * other DragDrop objects.</li>
+ * <li>handle element(s): The drag operation only occurs if the element that
+ * was clicked matches a handle element.  By default this is the linked
+ * element, but there are times that you will want only a portion of the
+ * linked element to initiate the drag operation, and the setHandleElId()
+ * method provides a way to define this.</li>
+ * <li>drag element: this represents the element that would be moved along
+ * with the cursor during a drag operation.  By default, this is the linked
+ * element itself as in {@link Roo.dd.DD}.  setDragElId() lets you define
+ * a separate element that would be moved, as in {@link Roo.dd.DDProxy}.
+ * </li>
+ * </ul>
+ * This class should not be instantiated until the onload event to ensure that
+ * the associated elements are available.
+ * The following would define a DragDrop obj that would interact with any
+ * other DragDrop obj in the "group1" group:
+ * <pre>
+ *  dd = new Roo.dd.DragDrop("div1", "group1");
+ * </pre>
+ * Since none of the event handlers have been implemented, nothing would
+ * actually happen if you were to run the code above.  Normally you would
+ * override this class or one of the default implementations, but you can
+ * also override the methods you want on an instance of the class...
+ * <pre>
+ *  dd.onDragDrop = function(e, id) {
+ *  &nbsp;&nbsp;alert("dd was dropped on " + id);
+ *  }
+ * </pre>
+ * @constructor
+ * @param {String} id of the element that is linked to this instance
+ * @param {String} sGroup the group of related DragDrop objects
+ * @param {object} config an object containing configurable attributes
