'zip' is a commonly used name for mapping a pair of ranges to ranges
of pairs in other languages; I see no reason not to use it. Also,
boost.iterator already has zip_iterator adapters.

Another (arguably) good name might be transpose, but that is probably
best left for ranges of ranges.

BTW, unpack already exists in boost as fusion::fused.
