template< class... Args > iterator emplace( const_iterator pos, Args&&... args );		(ya que C + +11)

Inserta un nuevo elemento en el contenedor directamente ante pos. El elemento se construye en el lugar, es decir, no copiar o mover las operaciones se realizan. El constructor del elemento se llama con el std::forward<Args>(args)... argumentos. El tipo de elemento debe ser EmplaceConstructible, MoveInsertable and MoveAssignable .
