+/**
+ * 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
