[boost] copy on write for std containers

Subject: [boost] copy on write for std containers

I wrote a couple of lines and replaced std::set and std::map with some 
copy-on-write-wrappers
and I got a dramatic speed improvement with the last gcc 4.5. I think.

My code was using recursive functions iterating over a tree returning and 
setting such objects.

I looked and it seems there is nothing like this in boost!

Ideally this should be an template argument for the std containers.
