elementsFromfunction
A source of element sets read from an address of your choosing, with whose data it is. The address is read through fetchElements, so its politeness rules apply (one request in two hours, a refusal is left alone for an hour,
nothing at rest); the sets are read once, when the source is added. The package has no address of its own and never asks one by itself.
