FS#827 - rbegin of FieldVector and ISTL classes has surprising semantics
User who did this - Markus Blatt (mblatt)
----------
This implementation is prescribed by the C++ standard:
24.4.1 Reverse iterators [lib.reverse.iterators]
Bidirectional and random access iterators have corresponding reverse iterator adaptors that iterate through
the data structure in the opposite direction. They have the same signatures as the corresponding iterators.
The fundamental relation between a reverse iterator and its corresponding iterator i is established by the
identity: &*(reverse_iterator(i)) == &*(i - 1).
