Snapshot Semantics for Temporal Multiset Relations

Summary: Identifies bugs in snapshot semantics for interval-timestamped multiset relations: snapshot aggregation and bag difference. Proposes a K-relations temporal model that fixes these issues and encodes snapshot semantics, with an efficient middleware and competitive native performance.
