 * @description Create a sortable table with multi-column sorting capabilitys
17
 *
18
 * @example $('table').tablesorter();
19
 * @desc Create a simple tablesorter interface.
20
 *
21
 * @example $('table').tablesorter({ sortList:[[0,0],[1,0]] });
22
 * @desc Create a tablesorter interface and sort on the first and secound column column headers.
23
 *
24
 * @example $('table').tablesorter({ headers: { 0: { sorter: false}, 1: {sorter: false} } });
25
 *
26
 * @desc Create a tablesorter interface and disableing the first and second  column headers.
27
 *
28
 *
29
 * @example $('table').tablesorter({ headers: { 0: {sorter:"integer"}, 1: {sorter:"currency"} } });

35
 * @param Object
36
 *            settings An object literal containing key/value pairs to provide

48
 * @option String cssDesc (optional) A string of the class name to be appended
49

52
 * @option String sortInitialOrder (optional) A string of the inital sorting
