The "dummy-files" folder made good sense prior to having tests, but now that we have that, I think we should remove the folder.

If such a folder is needed, it should be kept outside the Lannister repo.

from @Remi-Gau in #157

Oh and by the way we might have to deced how we want to write down the examples in our help section.

The way I have done it here is a way that allows to test the documentation itself: automatically reads the help section and checks that the examples are valid.

It is convenient but it looks like BEEEEEP in the read the docs...

Any idea?
