* allow usage of NiPoint3 and NiQuaternion in constexpr context * removed .cpp files entirely * moving circular dependency circumvention stuff to an .inl file * real world usage!!!!! * reverting weird branch cross-pollination * removing more weird branch cross-pollination * remove comment * added inverse header guard to inl file * Update NiPoint3.inl * trying different constructor syntax * reorganize into .inl files for readability * uncomment include * moved non-constexpr definitions to cpp file * moved static definitions back to inl files * testing fix * moved constants into seperate namespace * Undo change in build-and-test.yml * nodiscard
