# boost utility for simple iterator offsetting:
Function templates next() and prior()

Certain data types, such as the C++ Standard Library's forward and bidirectional iterators, do not provide addition and subtraction via operator+() or operator-().  This means that non-modifying computation of the next or prior value requires a temporary, even though operator++() or operator--() is provided.  It also means that writing code like itr+1 inside a template restricts the iterator category to random access iterators
