If this map contains an entry with a key equivalent to the specified key, assign the specified obj to the mapped_type of that entry, and return an iterator to that entry and false. Otherwise, insert a new entry into the map with the and return an iterator to that entry and true. obj is left in a (valid) unspecified state.
