The IntlIterator class

INTRODUCTION
	This class represents iterator objects throughout the intl extension whenever the iterator cannot be identified with any other object pro-
       vided by the extension. The distinct iterator object used internally by the foreach construct can only be obtained (in  the  relevant  part
       here) from objects, so objects of this class serve the purpose of providing the hook through which this internal object can be obtained. As
       a convenience, this class also implements the Iterator interface, allowing the collection of values  to	be  navigated  using  the  methods
       defined	in that interface. Both these methods and the internal iterator objects provided to foreach are backed by the same state (e.g. the
       position of the iterator and its current value).

	Subclasses may provide richer functionality.
