/*----------------------------------------------------------------------

InputSourceDescription: This is an "argument pack" structure, used to
pass a collection of related arguments to the constructors of InputSources.
InputSourceDescriptions should *not* be kept as data members, or stored
in any way.

InputSourceDescriptions should generally be passed by non-const reference,
so that the non-const reference data members can be used correctly.
