RFC: Collection framework.

[Jean-Philippe Bernardy]

Hello libraries folk,

Following popular demand, I've been working on a class-based
collections framework that I would like to submit for review.

The main goal is to have something usable right now, making use of
generally available haskell extensions for maximum
usability/portability ratio (or rather product).

Cheers,
JP.
