+/**
+ * This modification of DataTables' standard two button pagination controls
+ * adds a little animation effect to the paging action by redrawing the table
+ * multiple times for each event, each draw progressing by one row until the
+ * required point in the table is reached.
+ *
+ *  @name Scrolling navigation
+ *  @summary Show page changes as a redraw of the table, scrolling records.
+ *  @author [Allan Jardine](http://sprymedia.co.uk)
+ *
+ *  @example
+ *    $(document).ready(function() {
+ *        $('#example').dataTable( {
+ *            "sPaginationType": "scrolling"
+ *        } );
+ *    } );
