@Override
	public Iterator<ModuleOption> iterator() {
		return Collections.<ModuleOption> emptyList().iterator();
	}
Implementation of {@link ModuleOptionsMetadata} used when no explicit information about a module has been authored.

This implementation does not know how to list its module options and will pass thru the raw options data it receives
as options.
