/**
* Just like the _hidden title numeric sorting_ plug-in, this sorting plug-in
* will take the information to be sorted on from the title attribute of a span
* element. The only difference is that it is string based sorting rather than
* numeric.
*
* Note that the HTML5 `data-sort` attribute can be [used to supply sorting data
* to DataTables](//datatables.net/manual/orthogonal-data) and is preferable to
* using this method, which is therefore marked as deprecated.
*
* @name Hidden title string sorting
* @summary Sort data as a string based on an attribute on an empty element.
* @author [Allan Jardine](http://sprymedia.co.uk)
* @deprecated
*
* @example
* $('#example').dataTable( {
* columnDefs: [
* { type: 'title-string', targets: 0 }
* ]
* } );
