> There are cases where you would like to scan a table in reverse key order.
> For example: 
> Consider a table using an inverted timestamp key.
> This allows for very quick access to the latest records.
> But  It would be helpful to quickly access earliest records without having to:
> A) scan through all the records to build a collection to reverse sort
> B) store the table again using the reverse key
