    		 (depuis C++11)
    Insère un nouvel élément dans le récipient. L'élément est réalisé in-situ, c'est à dire pas de copie ou les opérations de déplacement sont effectuées. The constructor of the element type (value_type, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....

The constructor of the element type (value_type, that is, std::pair<const Key, T>) is called with exactly the same arguments as supplied to the function, forwarded with std::forward<Args>(args)....
