/**
 * @fileOverview  Plugin that changes the toolbar and maximizes the editor 
 *                for the big toolbar.
 * 
 *                You need a custom config to define the small and big toolbars.
 *                Also the maximize plug-in is needed but not the maximize button.
 *                For this plugin you should use the 'Toolbarswitch' button instead.
 * 
 *                CKEDITOR.replace('sometextcomponentname', {
 *               		customConfig: '/...custom_ckeditor_config.js'
 *               		toolbar: 'yoursmalltoolbarname', 
 *               		smallToolbar: 'yoursmalltoolbarname',
 *               		maximizedToolbar: 'yourbigtoolbarname' });
 *               
 *                Requires:
 *                - Maximize plugin. But not the button that goes with it. 
 *                - All toolbars used in the ckeditor instance have to use the 'Toolbarswitch' button instead.
 *                - A custom config to define the small and big toolbars.
 *                - function CKeditor_OnComplete(ckEditorInstance){ ... your own custom code or leave empty... }
 *                  This was added to the plugin for those that wrap the ckeditor in other java script to shield 
 *                  the rest of their code from ckeditor version particularities.
 *                - jQuery
