CFFs are ready, the result is stable for epsilon -> 0.

F110New does not work...

a,b,c) seem to work ok.

F100x, F210x, F201x (new implementations, dependent directly on x, xi
and betas) also work fine.

F211, F221, G still need to be fixed.

Now, poles should be at correct places.

Gsl still has some trouble with F110 and F211, and I do not know yet how
to fix that.

are still issues with the imaginary part. 
Probably a careful choice of regions will be needed.
