OK.

Well, I think it would be best instead of using feature groups and checks and 
these awful if constructs to have each weighter just calculate one function 
and have difficult flavours of weighters for each feature group. This would 
be nicer, cleaner design and probably faster, as the cost would be just 
incurred once.

It's appreciated. However, I see this issue quite orthogonal to the question 
if we include gife or not.

I am going home, so don't expect any more answers today. Have a nice evening.

Cheers,
Wolfgang
