[boost] [multi_index] ordered_index should be noncopyable?

I just had a really irritating time tracking down bad memory access in 
ordered_index because I foolishly wrote something like this:

     typedef client_set::nth_index<0>::type address_index_type;
     address_index_type addressIndex = clients_.get<0>();
     address_index_type::iterator iter = addressIndex.find(addr);

The problem here is that I got my addressIndex by value in the second 
line. I may be overlooking something here, but I think it might be 
useful to make ordered_index noncopyable so that this would be detected 
at compile time instead of runtime. I nearly threw my monitor out the 
window over this one.

Thanks,

Dylan Trotter
