+編集したバッファによって、対応する SessionInfo を呼び出す
+
+
+--------
+- 状況 -
+--------
+
+Session と emacs Buffer を一対一の関係にするっつーことで、
+バッファに対応する SessionInfo を生成した。これは
+
+SessionID, EditorID, Send Command List, Recv Command List
+
+で構成されている。
+
+--------
+- 流れ -
+--------
+
+1. ユーザが編集をおこなった
+2. そのバッファ名から、対応する SessionInfo を hash table より取得
+3. SessionInfo から sid, eid を取り出す
+
+4. 本番だと、その sid, eid を REPcommand に含めて SessionManager に送信
+
+まあ簡単ですねきっと
+
+---------
+- Usage -
+---------
+
+1. emacs を起動
+2. M-x load-file [Enter] で redit-test-change-session.el を指定する
+3. M-x redit-test-start で起動
+   このとき、バッファに hoge.c hoge.c<2> hoge.c<3> という3つのバッファができる
+   各バッファで編集を行うと、そのバッファに対応する sid eid が
+   *Messages* に表示される。対応する様子は .el を見てください。
