*
* @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.
* @example $(«#EDU_VEXCHANGERESULT4BYDAY1»).tablesorter({debug: true, decimal: ‘,’ });
* @desc Create a tablesorter interface and set a decimal delimeter ,
*
*
* @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»

* 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 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.
