Insert the specified value into this multimap. If a range containing elements equivalent to value already exists, insert the value at the end of that range. Return an iterator referring to the newly inserted value_type object. This method requires that the (template parameter) types KEY and VALUE both be copy-insertable into this multimap (see {Requirements on KEY and VALUE}).
