> ZippingIterator provides a way to simulatenously iterate over multiple 
> iterators of the *same-type.*
> The proposed pair iterator allows simultaneously iterating over two iterators 
> of different type, like the example below:
> {code:java}
> Iterator<L> leftIterator =  ...;
> Iterator<R> rightIterator = ...;
> PairIterator<L,R> pairIterator = PairIterator.of(leftIterator, rightIterator);
> while (pairIterator.hasNext()) {
>    ImmutablePair<L,R> item = pairIterator.next();
>    ...
> }{code}
>  
> Another convenience could be to use an Iterable for easy for-each constructs.
> {code:java}
> List<Integer> studentIds = ...
> List<String> studentNames = ...
> for (PairedItem<Integer, String> items : 
> IterableUtils.pairedIterable(studentIds, studentNames) {
>   Integer studentId = item.getLeft();
>   String studentName = item.getRight();
>   ...
> }
> {code}
>
