I uploaded updated version (I cleaned a code a bit). Plus test 
module, example and doc page (as you know, Dave, I am not that great 
in docs but I was trying to follow as much as possible to existent 
adaptors pages, so I hope it is not that bad). Location:

To Dave:

Could you please clarify, what non-portable rounding direction of 
negative numbers did you mean?

To Neal Backer:
I do not see what do we buy making Policy methods static. Dave could 
you clarify following question: since current design of 
iterator_adaptor allows implemnetation if adaptor policies both as 
member funtion and static function (since policy could be accessed 
through this or Base.policy()), is there any valid reasons to prefere 
one way over another?

Abould distance(): I do not see why do would you need distance to be 
always positive. Could you clarify Neal?

About std::copy test: I was able to compile and pass your test with 
curent version of adaptor. could you check that I got your intend 
correct?

Further comments are greatly appritiated.
