implement a latch class that could have the following interface


{{{
    class latch
    {
    public:
        latch(latch const&) = delete;
        latch& operator=(latch const&) = delete;

        latch(std::size_t count);
        ~latch();

        void wait();
        bool try_wait();
        template <class Rep, class Period>
        cv_status wait_for(const chrono::duration<Rep, Period>& rel_time);
        template <class lock_type, class Clock, class Duration>
        cv_status wait_until(const chrono::time_point<Clock, Duration>& abs_time);
        void count_down();
        void count_down_and_wait();
        void reset(std::size_t count);
    };
