Add example project file

This image shows many non-obvious features:

Can it be added in lieu of documentation?

Not sure if I understand what you mean. The given image is actually a screenshot of CrossLine with the demo repository (http://software.rochus-keller.ch/CrossLineDemo.cldb). Unfortunately there is nothing like a "documentation" yet, but the demo repository includes a lot of hints about what CrossLine can do and how to operate it.

Ah, I have missed the demo file! Perhaps add it to the git repository so it appears in local clones?

[rochus-keller]

Ok, I should do so.

[rochus-keller]

done.
