New description:
The patch defines several new classes for dealing with
- rooted recursive ordered trees (labelled and not)
- binary trees (labelled and not)
It also add the computation of the binary search tree and the decreasing
or increasing tree for a permutation
It finally defines the bijection to Dyck words

> Thanks -- I wait for Florent or Fred for approval of your change.
Thanks Viviane for this very good idea ! However, I feel that it should be
more documented as well as tested. That's why I revamped your patch in a
bigger patch. Please review it knowing that I'm Ok with your changes (the
tests I added pass :-).
