CombinedIterableView<T> class
A view of several iterables combined sequentially into a single iterable.
All methods and accessors treat the CombinedIterableView as if it were a single concatenated iterable, but the underlying implementation is based on lazily accessing individual iterable instances. This means that if the underlying iterables change, the CombinedIterableView will reflect those changes.
