Hi,
I have just checked in a new version that contains most of the syntax we
have discussed for repository and resolution. I am not done though
because I was sidetracked by the need to improve handling of validation,
error messages and quickfixes. After I did a few I did not like where
things ended up. There is now a much better solution.

- validation is simply written in the impl of the models (standard EMF)
- error messages and quick fixes can be associated with the validation
diagnostics from EMF

I added a few validations and a quick fix for the "unreachable case"
error (which now moved from the beelang package to where it belongs in
the backend).

Adding new validation should now be super simple, and it is possible to
customize the error messages in beelang to something that is more
relevant to the textual representation.

This also means that it easy for someone to help out with writing
validation :)
