[collections] FluentIterable

Hi,

today, I have committed a first version of a FluentIterable
(COLLECTIONS-464).

Example usage:

List<String> result =
  FluentIterable
    .of(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
    .filter(new Predicate<Integer>() {
        public boolean evaluate(Integer number) {
          return number % 2 == 0;
        }
      )
    .transform(TransformerUtils.stringValueTransformer())
    .limit(3)
    .toList();

will return [2, 4, 6]

I still need to add unit tests, but I'd love to get some feedback on the
current API.

Thomas

Are we going to reimplement the whole Java 8 Streams?
