boost::asio - Network Library modified by Terry - 3

boost::asio 내 맘대로 바꾼 버전 3번째.
client 부분임.

client 특징:
- 거의 모든 기능이 session 에 들어가 있기 때문에 초 간단함.
- connect 를 async / blocking 두 가지 모두 지원하지만 blocking 을 추천.
- 기본적으로 ioservice 가 iocp 를 사용하기 때문에, thread 를 돌림.
- 사용하는 쪽에서는 끝날 때까지 loop 돌려주다가 join 호출해서 종료하면 됨.
