Looks good, thanks! Instead of enlarging the README.md file though, could you create a samples directory and move it there, like @Neiko2002 did for LLVM and TensorFlow? Thanks!

Voilà :-)
This is based on the llvm samples project. Image is public domain from wikipedia, and this all works locally in my IDE provided that I configure the Run configuration as detailed in the class header.
Thanks for the feedback.
