Here's an input iterator I've used to test our algorithms. It lets
you wrap an ordinary pointer (not another iterator) into a sequence
of elements. We don't use container iterators (or any other parts
of the library) when testing algorithms to prevent bugs in those
areas from causing false negatives (or positives) in the tests.
