great !

hehe, yes, this is something I had in mind too :) Would be a very good
complement to lev-marq. Currently I'm using adolc (as you can guess
from the doc http://eigen.tuxfamily.org/dox/CustomizingEigen.html#CustomScalarType
!) but I'm missing higher level differentiation operators. Between
forward and backward differentiation the former seems to be quite easy
to implement but sometimes it is too limited. One more thing for the
long long term...
