/**

 * The DataTables core library provides the ability to set the ordering via the

 * `dt-api column().order()` method, but there is no plural equivalent. While

 * multi-column ordering can be set using `dt-api order()` that method requires

 * that column indexes be used.

 *

 * This plug-in provides the plural `columns().order()` method so you can set

 * multi-column ordering, while retaining the benefits of the `dt-api columns()`

 * selector options.

 *

 *  @name columns().order()

 *  @summary Apply multi-column ordering through the columns() API method.

 *  @author [Allan Jardine](http://sprymedia.co.uk)

 *  @requires DataTables 1.10+

 *  @param {string|array} dir The order to apply to the columns selected. This

 *    can be a string (`asc` or `desc`) which will be applied to all columns,

 *    or an array (again `asc` or `desc` as the elements in the array) which is

 *    the same length as the number of columns selected, and will be applied to

 *    the columns in sequence.

 *

 * @returns {DataTables.Api} DataTables API instance

 *

 *  @example

 *    // Apply multi-column sorting with a common direction

 *    table.columns( [ 1, 2 ] ).order( 'desc' ).draw();

 *

 *  @example

 *    // Multi-column sorting with individual direction for the columns

 *    table.columns( [ 1, 2 ] ).order( [ 'desc', 'asc' ] ).draw();

 *

 *  @example

 *    // Multi-column sorting based on a name selector

 *    table.columns( [ 'sign_up_date:name', 'user_name:name' ] ).order( 'desc' ).draw();
