+ * 
+ * @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.
