Proposed parser change: Make interactions syntactic sugar for Choice

[perneto]

It would be simpler for users of the Scribble AST to only have to deal with Choices, since Interactions are a special case of Choice where only one branch exists.

What do you think?

Hi Olivier

Not sure what the benefit of this would be, other than the slight simplification of the model.

I think it is better to have the model be a true reflection of the syntax, and also have the clarity of the separate interactions.
