Well, i didn't mean this version to be public, i submitted it to your repo for your review as i indicated in the pull request comment, because it's littered with comments so you could identify new code for easy comparison with the old.

If i knew of a way to edit the submitted file, with your permission i could overwrite the current code with the clean version.
