Hello,

only after a looong quest I realized that new IteratorChain(Iterator) 
will only iterate through the elements of the given iterator instead of 
expecting that each element is an iterator itself through which one 
iterates.

Am I blurred to expect such ?
I suppose that changing this behaviour would be a too strong API 
change... so should one do an IteratorThroughIterators?? I can offer a 
class... if wished.
