[ndnSIM] [EXT]Re: customise PIT size

[Junxiao Shi]

Hi Sai

If InterestLifetime is absent in the packet, it's equivalent to setting it
to 4000ms.

If the consumer transmits Interests more frequently,
* If the network & producer can satisfy these Interests quickly, PIT size
remains small.
* If some Interests are unsatisfied, PIT size increases.

Yours, Junxiao
