Insert the specified value into this unordered multiset. If one or more keys equivalent to value already exist in this unordered multiset, this method is guaranteed to insert value in a position contiguous to one of those equivalent keys. Return an iterator referring to the newly inserted value_type object that is equivalent to value. Note that this method requires that the (template parameter) type KEY be copy-insertable into this unordered multiset (see {Requirements on KEY}).
