/*
 * 1.获取LuaJIT！地址http://luajit.org/ 
  注意！！！！！============>>>>> uLua uses LuaJIT 2.0.2 which can be obtained from http://luajit.org/ 
  一定要下载LuaJIT 2.0.2 （当前release version 2.0.3） 
   
2.解压下载的压缩包 
  在terminal依次输入 
  cd /Users/YourAccount/Download/LuaJIT-2.0.2 
  make 
  sudo make install 
  luajit 
  如果能看到luajit的版本号，到此mac上luajit环境就ok了！！！ 
   
3.通过luajit对所有lua文件进行编译，生成bytecode二进制文件 
  find . -name "*.lua" -exec luajit -b {} {}.out \; 
  {}.out  至于这个后缀，本人其实建议还是用lua 
   
4.最后就是既关键！又简单！的一步！ 
  大家使用ulua，一般调用的是Lua.cs里的LuaState实例的DoString、DoFile 
  如果想使用LuaJIT的bytecode文件，只需要调用LuaDLL.luaL_dofile(IntPtr luaState, string fileName) 
   
本人亲测win、mac、android、ios均通过测试！！！解决了lua加密的问题！嘿嘿！ 


本次测试正好确认了一件事！那就是ulua插件提供的库里已经把LuaJIT打进去了！
