* 
* @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 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:"integer"}, 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 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.
*         Default value: true
* 
* @option Boolean debug (optional) Boolean flag indicating if tablesorter
*         should display debuging information usefull for development.
