+ * Iter provides utilities for working with {@link Iterator}s.
+ *
+ * Iter should never be used as a return type or parameter type in the
public contract of a class. It is only to be used
+ * inside implementation code and is instantiated only to allow
method-chaining as part of a calculation.

IMO `Iter` is better than `ExtendedIterator` (more general, separated out)
and should be used on general iterators. `ExtendedIterator` exists in jena-core
and Graph API only and as a Triple iterator.
As ExtendedIterator is exposed, it can't be changed.
So if and where working on triple iterators out of Graph, use
ExtendedIterator, else Iter.
