The IteratorIterator class

INTRODUCTION
	This  iterator	wrapper  allows  the  conversion of anything that is Traversable into an Iterator. It is important to understand that most
       classes that do not implement Iterators have reasons as most likely they do not allow the full Iterator	feature  set.  If  so,	techniques
       should be provided to prevent misuse, otherwise expect exceptions or fatal errors.
