/**
 * @summary     ConditionalPageLength

 *
 * This feature plugin for DataTables hides the page length control when the amount
 * of pages is <= 1. The control can either appear / disappear or fade in / out.
 *
 * Based off conditionalPaging by Matthew Hasbach (https://github.com/mjhasbach)
 * Reference: https://github.com/DataTables/Plugins/blob/master/features/conditionalPaging/dataTables.conditionalPaging.js
 *
 * @example
 *    $('#myTable').DataTable({
 *        conditionalPageLength: true
 *    });
 *
 * @example
 *    $('#myTable').DataTable({
 *        conditionalPageLength: {
 *            style: 'fade',
 *            speed: 500 // optional
 *        }
 *    });
 *
 * Conditionally hide the Page Length options that are less than the current result size.
 * @example
 *    $('#myTable').DataTable({
 *        conditionalPageLength: {
 *            conditionalOptions: true
 *        }
 *    });
