16. change header types.hpp to metafunctions.hpp
17. post-review question: should Range mean lowest common denominator? or
perhaps Forward Range? problem with not being explicit.
18) change use of types.hpp -> metefunctions.hpp
18. maybe iterator_range operator==() should be defined when rhs or lhs
take a forward range argument; this comparison function should
then call std::lexigraphical_compare(....). Example:
sub_range<string> sub = ...;
if( sub == "foo" )
