[ndnSIM] CsTracer has no CacheHit

[DJEMAA Adel]

Hi liu hu,
It depends on the Consumer application you've used, for example ConsumerCBR
will always give you Cache hit=0, since all interest packets are different.
Try to change the consumer application to ConsumerZipfMandelbrot for
example, and fix the Number of different content (sequence numbers) at a
low value, so that the same interests will be requested many times. A such,
the cache hit ratio is supposed to be positive.
Hope that will help.
