It does nothing more than pulling 'std::iterator' into namespace boost and including standard libraries 'iterator' and 'cstddef'. This library only takes advantage of the included headers. OTOH, pulling 'std::iterator' into boost generates deprecation warnings in MSVC 14.1 when compiling in C++17 mode. Besides that, Boost's 'iterator.hpp' is deprecated, too.
