//用法：非win8仅需调用RegisterFileRelation函数即可
//win8需自己定义下面HASH值，具体值可以通过如下方式获取：
//以管理员权限运行一次RegisterFileRelation（参数要给对）
// 然后找到要关联的文件选择默认程序
// 再到注册表HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts\\你的后缀名\\UserChoice中找到Hash这个键值
// 将键值填入下面HASH宏定义中即可

//English version:
//usage: if you don't use win8 & win8.1 just call RegisterFileRelation,
//otherwise, you should first call RegisterFileRelation in your app as admin, 
//then find one file that has the wanted ext, used OS's methods(such as right button -> open with)to assocate this file to your app.
//now find the Hash Key value in HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer\\FileExts\\[your ext]\\UserChoice
//change the HASH defination at follow, then you can assocate your file in any win8 PC!
