Using Context with multiple Revit instances open

[atharkes]

Looking at this repo for the first time so correct me if I'm wrong, but it seems like the Context class assumes there is only a single instance of Revit running (as seen by the single static UiApplication property). I'm wondering if we could generalize this somehow to handle all running instances of Revit.

Each instance of Revit creates its own domain and, accordingly, a new instance of UiApplication. Different instances of Revit will have different instances of UiApplication
