Jon, I don't know of an obvious way to do this. I guess you could create a map from pair<cell_iterator, face_index> to an index (just increment a value from 0). Then you can store data in a normal vector. For only considering a face once, you need to have a tie breaker when filling this map. You can look how we do it in meshworker for example (always from the finer cell and from the lower cell index if on the same level for example).
I hope that helps.
