Missing functions

[copy]

I've developed a small application using containers, and found some functions that I missed:

• CCFloat.round : float -> float – a version that returns an int would also be useful
• CCVector.append_gen : 'a CCVector.vector -> 'a gen -> unit
• CCList.{first, last} : 'a list -> 'a option
• CCHashtbl.{to_gen, values_gen, keys_gen} – I guess these can't be implemented without using an intermediate list. They would still be nice to have so that I don't need to update my code when the standard library provides a more efficient way to implement them

I implemented everything but the Hashtbl functions. It's indeed not efficiently implementable, and it's not much more verbose to write CCHashtbl.values_list |> Gen.of_list, which at least makes the cost explicit; even if/when the stdlib starts providing efficient versions, it will not be portable, so I'd advise to use Sequence for now.

Feel free to re-open if you disagree, I'm not totally opposed to it :-)

No, I agree with your reasoning.

Thanks for implementing the functions!
