用于实现类似需求：
准入授权配置文件有时候分了好几个维度进行配置，例如 company|product|sys这种格式的配置:
1.配置 "sina|weibo|pusher" 表示 sina公司weibo产品pusher系统能够准入，而"sina|weibo|sign"不允许准入
2.配置 "sina|*|pusher” 表示sina公司所有产品的pusher系统都能够准入
3.配置 “*|*|pusher” 表示所有公司的所有产品的pusher系统都能够准入

以上需求及下面测试代码来源于网络：http://www.cnblogs.com/Creator/archive/2013/03/25/2981186.html；
其中fnmatch是Linux下特有函数，因此从Google-glog中摘取了部分跨平台实现，请看：https://code.google.com/p/google-glog
