If a key equivalent to the specified key already exists in this hash-table, load false into the specified isInsertedFlag and return a pointer to the existing entry. Otherwise, insert into this hash-table a newly-created value_type object, constructed from std::forward<KEY>(key) and the specified args, load true into isInsertedFlag and return a pointer to the newly created entry. Use the optionally specified hint as a starting place for the search for the existing key.
