code: @Deprecated
    public static <InType, OutType> Iterable<OutType> applyOneToManyTransform(
        final Iterable<InType> input,
        final Function<? super InType, ? extends Iterable<OutType>> function) {
      return FluentIterable.from(input)
          .transformAndConcat(function);
    }
docs: Applys a one-to-many transform to each element of an {@code Iterable} and concatenates all the
  results into one {@code Iterable}. This is done lazily.
  
  @deprecated Prefer {@link FluentIterable#transformAndConcat(Function)} now that it
  exists.
