Get a reversed view of this index

<p>
This affects iteration as well as all the navigation and sub-ranging methods. E.g.,
{@link #lowerKey(Object)} in the reversed view will behave like {@link #higherKey(Object)} in
the original. In other words, the returned index is equivalent to the original, but with a
negated comparator. Calling {@link #descending()} on the returned view will return a view
equivalent to the original.

@return the reversed view
