Change macOS example project bundle ID to something else

[AnZhg]

Hi Kostub, I did some initial work to port this great project to macOS. However, I mistakenly used my own bundle ID prefix in the macOS project. ("AnZhg.MacOSMath") Can you change it to something else? Thank you! Not very urgent, but I'd like it to be consistent with iOS sample project bundle ID or something similar.
