/**
 * Change the number of records that can be viewed on a single page in 
 * DataTables.
 *
 * DataTables 1.10 provides the `dt-api page.len()` method to get and set the
 * page length using the built-in API. As such this method is marked deprecated,
 * but is available for use with legacy version of DataTables. Please use the
 * new API if you are used DataTables 1.10 or newer.
 *
 *  @name fnLengthChange
 *  @summary Change the paging display length

 *  @example
 *    $(document).ready(function() {
 *        var table = $('#example').dataTable();
 *        table.fnLengthChange( 100 );
