// sortTable(id, col, rev)
//
//  id  - ID of the TABLE, TBODY, THEAD or TFOOT element to be sorted.
//  col - Index of the column to sort, 0 = first column, 1 = second column,
//        etc.
//  rev - 0 = use normal order, except when the column is clicked a second time
//				1 = sort always up. 2 = sort always down.
//
// Note: the team name column (index 1) is used as a secondary sort column and
// always sorted in ascending order.
// alternative: datatables.net?
