As there are no functors for computing the minimum and maximum, we convert the std::max and std::min function pointers to functors (which is not really nice.) Previously we were somehow tricked into using std::greater and std::less, which of course do return true or false and not what we need. Additionally, do more excessive testing with different ranges.
