Continuous integration

The Github repository has two workflows in "Actions" defined in the Yaml files in ./github/workflows/
The Manual workflow can be used to run (click on "Run Workflow" button) the unit tests in the Github pipeline. NB : Refresh the HTML page if nothing moves.
The other workflow Node.js CI is used for continuous integration.
