This looks pretty cool. I hope to be able to take a look at it during 
the christmas holidays.

I cannot comment in details yet, but it seems to address several issues 
I encountered myself while implementing the neighborhood iterator (which 
I will try to update to use the new one).

One question: which CPU/platform did you test it on ?

cheers,

David
