Yes, that is what I had in mind, but I realize that "onVersion"
doesn't show that. It should be "toVersion", and then it should work
exactly as you say.
Good, but should'nt it be something like
"betweenVersions("predecessor","successor"), i.e. one edge in the history?
Why? If I have 1.1 then 1.2 and then 1.3, but a schema change only
occured in 1.4, why would I have to specify the start point instead of
just saying "in 1.4 this change happened". What help would the
predecessor info give you?
