旅游区景点导游系统

针对游客的不同需求，设计一款旅游区景点导游系统。

基本功能及要求如下： 

1. 提供用户操作的菜单和界面，实现系统的所有功能。
2. 旅游区所有景点信息，要求以文件的形式存储（如文本文件），格式自行设计。
3. 提供对旅游区所有景点信息的查询、编辑功能，可进行查找、添加、删除和修改等操作，修改后的信息需要保存回文件。
4. 提供旅游区当前景点显示功能，要求能显示游客当前所在景点及所有与游客所在景点相邻景点信息。
5. 提供查询从旅游区每个景点出发到其他任一景点的最短简单路径及距离的功能。
6. 提供查询旅游区任意两个景点之间所有简单路径及距离、最短简单路径及距离的功能。
7. 提供最佳游览路线推荐功能，即确定从某一景点出发，经过景区所有景点（景点可以重复）且距离最短的游览路线。
