Graphical grouping and relations.

[Mannshoch]

I like the DSL and the possibilities of the Graphic user interface.
If possible I would like to see a way to modify the DSL file in the GUI.
I have a case where I plan and discuss a new structure with others. And here we move things a lot across.
It would be nice If I could create and remove groups on the fly and also connect and name relation ships.

At moment I work only with group and element and move them around. At the end groups and elements get replaced by their correct model.
