Xavier,
my fault. I fell into the "better is enemy of good" trap. Namely,
I though "Ok, I'll integrate Xavier's pricer in the library when we switch
finite differences to the new framework---no need to do it twice." But of
course the switch is taking longer than expected, and your code is waiting
in limbo. I should have known better...

Yes, I second that. Switching the existing pricers to the new framework
doesn't exactly strike me as an introductory project, or a 10-hours one.
At least, I know it would take _me_ more than 10 hours, and I know the library.
Bye,
Luigi
P.S. Oh, and yes, I'll try and add Xavier's code to the library this time...
