Tests for one object being less than a second object.

template<class Type1, class Del1, class Type2, class Del2>
    bool operator<(
        const unique_ptr<Type1, Del1>& _Left,
        const unique_ptr<Type2&, Del2>& _Right
    );
template<class Ty1, class Ty2>
    bool operator<(
        const shared_ptr<Ty1>& _Left,
        const shared_ptr<Ty2>& _Right
    );
