3'文件摘要：INI类
4'文件版本：3.0
5'文本创建日期：2:17 2004-12-14
6'================= 属性说明 ================
7'INI.OpenFile = 文件路径（使用虚拟路径需在外部定义）
8'INI.CodeSet = 编码设置，默认为 GB2312
9'INI.IsTrue = 检测文件是否正常（存在）
10'================ 方法说明 =================
11'IsGroup(组名) 检测组是否存在
12'IsNode(组名,节点名) 检测节点是否存在
13'GetGroup(组名) 读取组信息
14'CountGroup() 统计组数量
15'ReadNode(组名,节点名) 读取节点数据
16'WriteGroup(组名) 创建组
17'WriteNode(组,节点,节点数据) 插入/更新节点数据
18'DeleteGroup(组名) 删除组
19'DeleteNode(组名,节点名) 删除节点
20'Save() 保存文件
21'Close() 清除内部数据（释放）
