   * @description Create a sortable table with multi-column sorting capabilitys
   *
   * @example $('table').tablesorter();
   * @desc Create a simple tablesorter interface.
   *
   * @example $('table').tablesorter({ sortList:[[0,0],[1,0]] });
   * @desc Create a tablesorter interface and sort on the first and secound column in ascending order.
   *
   * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });
   * @desc Create a tablesorter interface and disableing the first and secound column headers.
   *
   * @example $('table').tablesorter({ 0: {sorter:"integer"}, 1: {sorter:"currency"} });
   * @desc Create a tablesorter interface and set a column parser for the first and secound column.

   *
   * @param Object settings An object literal containing key/value pairs to provide optional settings.
   *
   * @option String cssHeader (optional) 			A string of the class name to be appended to sortable tr elements in the thead of the table.
   * 												Default value: "header"
   *
   * @option String cssAsc (optional) 			A string of the class name to be appended to sortable tr elements in the thead on a ascending sort.
   * 												Default value: "headerSortUp"
   *
   * @option String cssDesc (optional) 			A string of the class name to be appended to sortable tr elements in the thead on a descending sort.
   * 												Default value: "headerSortDown"
   *
   * @option String sortInitialOrder (optional) 	A string of the inital sorting order can be asc or desc.
   * 												Default value: "asc"
   *
   * @option String sortMultisortKey (optional) 	A string of the multi-column sort key.
   * 												Default value: "shiftKey"
   *
   * @option String textExtraction (optional) 	A string of the text-extraction method to use.
   * 												For complex html structures inside td cell set this option to "complex",
   * 												on large tables the complex option can be slow.
   * 												Default value: "simple"
   *
   * @option Object headers (optional) 			An array containing the forces sorting rules.
   * 												This option let's you specify a default sorting rule.

   * 												This option let's you specify a default sorting rule, which is prepended to user-selected rules.
   * 												Default value: null
   *
    * @option Array sortAppend (optional) 			An array containing forced sorting rules.
   * 												This option let's you specify a default sorting rule, which is appended to user-selected rules.
   * 												Default value: null
   *
   * @option Boolean widthFixed (optional) 		Boolean flag indicating if tablesorter should apply fixed widths to the table columns.
   * 												This is usefull when using the pager companion plugin.
   * 												This options requires the dimension jquery plugin.
   * 												Default value: false
   *
   * @option Boolean cancelSelection (optional) 	Boolean flag indicating if tablesorter should cancel selection of the table headers text.
