/**
 * This function will restore the order in which data was read into a DataTable
 * (for example from an HTML source). Although you can set `dt-api order()` to
 * be an empty array (`[]`) in order to prevent sorting during initialisation,
 * it can sometimes be useful to restore the original order after sorting has
 * already occurred - which is exactly what this function does.
 *
 * Please note that this plug-in can only be used for client-side processing
 * tables (i.e. without `serverSide: true`).
