This was a little project as part of training as a developer at GFN AG, Germany
I have done my own design on this programm much of methods are rewritten by myself (e.g.: my custom messages) develloped by M. Gießler on Dec 2019
surely, there could be much more methods, but i decide to finish it here.
NOTE that you need a local Mongo DB (https://www.mongodb.com/) to start the programm !!!
