[ndnSIM] ndnSIM compatibility with packet loss simulation

Hi Saran,

Do you need a precise control over which error rate is set on which link, or you want to just set the same error rate on all links?

I think, it could be possible and relatively simple to add this function to AnnotatedTopologyReader.  Are there just two parameters you mentioned or there is something else to be configured?  I see that there are also other error models available in NS-3 (BinaryErrorModel, ListErrorModel, and ReceiveListErrorModel).  Would it make sense to create a solution to allow any of these models?   I'm not quite sure how exactly to extend the reader, so the solution is general enough...
