/**
* @fileOverview jQuery adapter provides easy use of basic CKEditor functions
* and access to internal API. It also integrates some aspects of CKEditor with
* jQuery framework.
*
* Every TEXTAREA, DIV and P elements can be converted to working editor.
*
* Plugin exposes some of editor's event to jQuery event system. All of those are namespaces inside
* ".ckeditor" namespace and can be binded/listened on supported textarea, div and p nodes.
*
* Available jQuery events:
* - instanceReady.ckeditor( editor, rootNode )
* Triggered when new instance is ready.
* - destroy.ckeditor( editor )
* Triggered when instance is destroyed.
* - getData.ckeditor( editor, eventData )
* Triggered when getData event is fired inside editor. It can change returned data using eventData reference.
* - setData.ckeditor( editor )
* Triggered when getData event is fired inside editor.
*
* @example
* <script src="jquery.js"></script>
* <script src="ckeditor.js"></script>
* <script src="adapters/jquery/adapter.js"></script>
