Graph versioning and parallel timelines?

[davideps]

I'm running a simulation that will build a graph over time. At times, the simulation branches and builds multiple versions of the graph. I'd like to query the result to see (for example) the version of the graph corresponding to BRANCH a/b/c TIME 12. How should I approach such versioning in agensgraph? Some databases use timetrees or parameters on nodes and edges or partitioning.
