Hi Paul,

Thanks a lot for your comments.
I have tried to write some sample program to illustrate a possible use
of the 'nonfinite_num_facets.hpp' header by Johan Rade.
It is attached. Hope it could help other people.
As I am not aware of practise concerning such kind of 
contribution/sample bits,
maybe you could help to copy it in some Boost contribution repository or 
give
me the procedure to do it by myself.

regards

frc
