What to do!

게시판 구현하기 1개의 글
: seq(글 번호), title(글 제목), writer(작성자), contents(글 내용), regdate(작성 일자), hitcount(조회수)
1. 글쓰기 입력: 글 제목, 작성자, 글 내용 => Board객체 생성
2. 전체 출력 글 번호 글 제목 작성자 작성자 일자 조회수
3. 글 세부조회 글 번호를 통해 해당 글 조회 글 번호, 글 제목, 작성자, 글 내용, 작성 일자, 조회수 => 1개 Board객체
4. 수정/삭제
5. 검색(제목, 작성자) 내가 원하는 글들만 출력
6. 정렬(기본) : 최근 입력 순서(내림차순)
7. 댓글 : 글 세부 기능 => 댓글 쓰기 , 해당 글 세부 보기 => 댓글 목록
