Improve documentation for "Initialisation with 'new'" example

[wwuck]

The "Initialisation with 'new'" example page at http://datatables.net/release-datatables/extensions/TableTools/examples/new_init.html could do with an update to show where the TableTools options should be set. Currently, there's no way to know that you need to move the TableTools options from the DataTable() method to the TableTools() method.

eg.

$(document).ready(function() {
    var table = $('#example').DataTable({
        // don't set TableTools options here
    });
    var tt = new $.fn.dataTable.TableTools( table, {
        // set TableTools options here instead
    } );

    $( tt.fnContainer() ).insertAfter('div.info');
} );

Good point - thanks!
