-/**
- * The splitter() plugin implements a two-pane resizable splitter window.
- * The selected elements in the jQuery object are converted to a splitter;
- * each selected element should have two child elements, used for the panes
- * of the splitter. The plugin adds a third child element for the splitbar.
- *
- * For more details see: http://methvin.com/splitter/
- *
- *
- * @example $('#MySplitter').splitter();
- * @desc Create a vertical splitter with default settings
- *
- * @example $('#MySplitter').splitter({type: 'h', accessKey: 'M'});
- * @desc Create a horizontal splitter resizable via Alt+Shift+M
- *
- * @name splitter
- * @type jQuery
- * @param Object options Options for the splitter (not required)
- * @cat Plugins/Splitter
- * @return jQuery
