JSONCONS_N_MEMBER_NAME_TRAITS does not compile

[alokpr]

JSONCONS_N_MEMBER_NAME_TRAITS produces compile error. It also does not have any test coverage.

JSONCONS_ALL_MEMBER_NAME_TRAITS works fine.

struct Person {
  std::string name;
  std::string surname;
};

JSONCONS_N_MEMBER_NAME_TRAITS(Person, 1, (name, "n"), (surname, "sn"))

int main() {
  std::string data = R"({"n":"Rod"})";
  auto person = jsoncons::decode_json<Person>(data);

  std::string s;
  jsoncons::encode_json_pretty(person, s);
  std::cout << s << "\n";
}

FAILED:

Thanks for reporting this, fixed on master, and your test case added.

Thanks a lot for the quick fix!

Great project BTW. I finally decided on jsoncons after evaluating quite a few json libraries out there.
