 Based on the ideas in N3600- C++ Latches and Barriers  http://www.open-

 std.org/jtc1/sc22/wg21/docs/papers/2013/n3600.html

 implement a completion_latch class that could have the following interface


 {{{
     class completion_latch
     {
     public:
         typedef 'implementation defined' completion_function;

         completion_latch(completion_latch const&) = delete;
         completion_latch& operator=(completion_latch const&) = delete;

         completion_latch(std::size_t count);
         template <typename F>
         completion_latch(std::size_t count, F&& funct);
         ~completion_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);
         template <typename F>
         completion_function then(F&& funct);
     };

 }}}
