SLV level 2 example

https://github.com/COST-ELTeC/ELTeC-slv has in the level2 directory (at least 1) file with linguistic annotation. I'd be thankful if it were vetted and them maybe included here as an example.
(I hope an issue is ok for such a request, I don't seem to have push privileges and a pull request seems a bit over the top).
