packedElementsFromfunction

A source of element sets read from a packed catalogue file (packCatalogue, gzipped or not) at an address you choose: up to 200,000 objects, six-digit catalogue numbers included. The file is asked for once, when the source is added, and nowhere else: no cookies and no referrer are sent, only https (or http on localhost) is used, a redirect or any answer but 200 is a failed read, and an answer over maxBytes is refused. Nothing is kept between page loads and nothing is asked on a timer. The package has no address of its own; a site that hosts these files says whose data they are in info.
