iterator_size

Description
Could you add iterator_size to boost/iterator/iterator_traits.hpp?
It'd be size_t for pointers and, since std::iterator_traits does not yet define size_type, make_unsigned iterator_difference.
It'd be used for the size of a range as given by a valid pair of iterators.

IMO, it's more accurately a range trait. I don't see a context in which you'd speak of an "iterator's size type" outside of a range.

True, but the same applies to difference_type.
I don't really mind where this gets implemented though.

It looks like it's already implemented via boost/range/size_type.hpp, no? Would you be okay with closing this ticket?

This seems to be more appropriately placed within the Range library than the Iterator library, doesn't it?
