[ndnSIM] problem with setExclude

[Alex Afanasyev]

Hi Sugan,

I would answer your question slightly differently.  You should not directly use setExclude, as it is more or less an implementation detail.  Exclude class proves a few methods to be used instead: excludeOne, excludeRange, excludeBefore, and excludeAfter.

So the first time, one Data "/service/1" comes back, and consumer excludes it and send a Interest again. Repeat this until all the producers are discovered.
