  * @description Create a sortable table with multi-column sorting capabilities
  *
  * @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 column headers.
  *
  * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });
  * @desc Create a tablesorter interface and disableing the first and second  column headers.
  *
  * @example $('table').tablesorter({ headers: { 0: {sorter:"digit"}, 1: {sorter:"currency"} } });
  * @desc Create a tablesorter interface and set a column parser for the first and second 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.
  *         Default value: null
  *
  * @option Array sortList (optional) An array containing the forces sorting rules. This option let's you specify a default sorting rule.
  *         Default value: null
  *
  * @option Array sortForce (optional) An array containing forced sorting rules. This option let's you specify a default sorting rule,
  *         which is prepended to user-selected rules.
  *         Default value: null
  *
  * @option Boolean sortLocaleCompare (optional) Boolean flag indicating whatever to use String.localeCampare method or not.
  *         Default set to true.
  *
  * @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 useful 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.
  *         Default value: true
  *
  * @option Boolean debug (optional) Boolean flag indicating if tablesorter should display debuging information usefull for development.
