 * 		type array|string Order type, e.g. shop_order or shop_order_refund
 * 		parent int post/order parent
 * 		customer int|string|array User ID or billing email to limit orders to a

 * 			e.g. [email protected], 1, array( 1, 2, 3 ), array( array( 1, '[email protected]' ), 2, 3 )
 * 		limit int Maximum of orders to retrieve.
 * 		offset int Offset of orders to retrieve.
 * 		page int Page of orders to retrieve. Ignored when using the 'offset' arg.
 * 		exclude array Order IDs to exclude from the query.
 * 		orderby string Order by date, title, id, modified, rand etc
 * 		order string ASC or DESC
 * 		return string Type of data to return. Allowed values:
 * 			ids array of order ids
 * 			objects array of order objects (default)
 * 		paginate bool If true, the return value will be an array with values:

 * 			'max_num_pages' => max number of pages found

 * @return array|stdClass Number of pages and an array of order objects if
