Class IterablePair<A,B>

An Iterable which is backed by two other Iterables, whose iteration produces a Pair of objects corresponding to those given by the two respective iterations of the backing Iterables. That is: the two backing Iterables are iterated in synchrony, and their elements combined into a single Pair accessor object.

When two Iterables are given which produce an unequal number of elements, the iteration of the IterablePair ends when either of the two backing iterations ends.
