  /**
   * 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/jquery/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
