BidiIterableReturns a reverse version of this iterable that can be used
forwards and backwards. In other words, an iterator provided by
the reverse iterable will delegate its hasNext()
and next() invocations to
BidiIterator.hasPrevious() and BidiIterator.previous()
respectively.
This allows clients to iterate backwards by means of the enhanced for-loop:
for(T t: iterable.reverse()) {
// do something with t
}
