As far as I can tell, EchoIteratorDecorator is functionally identical to IteratorDecorator from includes/libs/iterators/ in core, so why have a separate copy? (EchoIteratorDecorator does pass through the return value of next() or rewind(), if any, but there shouldn't be any per the Iterator interface.) Change-Id: Ic763ec19c15f67d9c9b42ebffb88c52b9056ed22
