EXCEL as a REST application

Thinking about using excel as user interface is sure an original idea: I like the idea behind it!

• I skipped the docker piece and tested with a local instance
• It was easy to install and to run (except EXCEL setup)
• using EXCEL as unser interface is an funny idea
• you get offered a broad selection of various ways to interact.
• I was really impressed by this approach

the layout of the repo is non-standard.
a PR to fix is hanging for a long time
so it is a test of your skills in using docker.
as i refuse to use MS Office products the test ended.
Open Office is obviously not compatible to use the scripts.
