 * ================================================================
 * 
 * 说明:
 * 
 *        1.命名空间: Emao_CfgManager
 *          类名    : CfgManager
 * 
 *         2.声明: CfgManager cm = new CfgManager();
 * 
 *        3.具体方法自己看代码吧哈。简单的很。
 *                
 *                  分别是：add() readAll() writeAll()
