Since a few weeks, I am working on the differentiation API (it was
surprinsingly difficult to implement Dan Kalman's paper efficiently).
The core part is almost ready, as per Julien and Phil comments. I hope
to commit a first working set in a few days now.

I would like to have this API and some preliminary implementations
included in 3.1. The ones I would like to have are the basic building
blocks supporting direct implementation by user and finite differences
at least for small derivation orders.
