The standard stream iterators don't quite work for us.  On systems which implement <code style="white-space: normal">wchar_t</code>
as unsigned short integers (E.G. VC 6) they didn't function as I expected. I also made some
adjustments to be consistent with our concept of Dataflow Iterators.  Like the rest of our
iterators, they are found in the namespace <code style="white-space: normal">boost::archive::interators</code>
