Represents an entry in the Interest table (PIT).
An Interest table entry represents either a pending Interest or a recently satisfied Interest. Each entry contains a collection of in-records, a collection of out-records, and two timers used in forwarding pipelines. In addition, the entry, in-records, and out-records are subclasses of StrategyInfoHost, which allows forwarding strategy to store arbitrary information on them.
