I've always used iterator_facade [1] or iterator_adaptor [2]. This is the first
time I hear about iterator_helper.

In terms of choosing between iterator_facade and iterator_adaptor, I believe
iterator_adaptor is meant to be used when your iterator wraps some underlying
iterator, and iterator_facade when your iterator does something different/more
than that. iterator_adaptor is implemented using iterator_facade.
