An Iterator implementation that wraps other Iterators, and presents them all as one continuous Iterator. When any method from Iterator is called, we delegate to each wrapped Iterator in turn until all wrapped Iterators are exhausted.

An JoinedIterator is an Iterator that wraps a number of Iterators. This class makes multiple iterators look like one to the caller. When any method from the Iterator interface is called, the JoinedIterator will delegate to a single underlying Iterator. The JoinedIterator will invoke the Iterators in sequence until all Iterators are exhausted.
