Hey @bitcurious, thanks a lot for your contribution! That is an awesome piece of work. We will take a look into the code in the upcoming days. In the meantime, if you could fix the linter issues it would be really helpful. You can autoformat based on .clang-format file and CPPLINT.cfg located at the root of the repository.
