temporarily revert to older traits strategy for DurationRange/DateRange, and DateTimeRange - due too the bugs it aggratvated with depednecy on k(DATETOME)::kMin/kMax - cross module obj construction. Must fix that first
hopefully support constexpr/and const ref version of kMin/kMax for Date object (ModuleInitializer) - to break down problems with module init
Merge branch 'DEV' of github.com:SophistSolutions/Stroika into DEV
use ModuleInitializer<> trick in Duration module - to hopefully avoid deadly embrace issues on construction order
