/**
 * A dummy superclass to support GWT serialization of the element types of a {@link HashMultimap}.
 * The GWT supersource for this class contains a field for each type.
 *
 * For details about this hack, see {@code GwtSerializationDependencies}, which takes the same
 * approach but with a subclass rather than a superclass.
 *
 * TODO(cpovirk): Consider applying this subclass approach to our other types.
