 * A factory of ObjectProducers that read objects from files.
 *
 * The files may be a single file, or multiple (split) files,
 * with binary or ascii content.
 *
 * This is a singleton class, call using FileProducerFactory::instance().

 * The new object producers returned must be deleted by the caller.
