MayaAPI官方案例asciiToBinary的修改，实现ma和mb格式互转

1、直接上代码

2、我编译好的程序。

3、使用说明（这里只提供了初略的功能，更多功能需要结合自己的流程，本次演示最重要的互转功能）

a、把asciiToBinary.exe复制到和maya.exe同级目录下，比如我的是：‘D:\Program Files\Autodesk\Maya2015\bin”

b、把需要转换的文件复制到和maya.exe同级目录下，比如我的是：‘D:\Program Files\Autodesk\Maya2015\bin”

c、使用命令行cd到maya.exe目录下，使用命令行：asciiToBinary.exe “xxx.ma”（ma转mb）或asciiToBinary.exe “xxx.mb”（mb转ma）
