chore: pulled in original sources - v2

This is the second attempt of a similar PR from before.
Contains the code donated by Accenture as part of the lab
Commit history could not be kept due to lack of signatures.
List of contributors were attached in the README as thanks to the original contributors.

  Date:   Wed Oct 23 16:16:24 2019 +0200
