Hmmm... You're removed the boost/iterator_adaptors.hpp file
intentionally, right? This makes it even more problematic, because,
there is no chance to circumvent compilation errors.
What about re-introducing the boost/iterator_adaptors.hpp file:

#include <boost/iterator/iterator_adaptor.hpp>

This would allow for some version tracking and a smooth migration path
for those libraries, willing to support both, the new _and_ the old
iterator libs. Thought's?
