[ndnSIM] "Incompatible types" error in V2vTracer::Connect()

[John McKendry]

I am trying to run the car-push scenario from the car-to-car ndnSIM code
from https://github.com/cawka/ndnSIM-nom-rapid-car2car . The car-relay
example is working, but I get an "Incompatible Types" error when I try to
run car-push. The error comes from the first line in V2vTracer::Connect(),
which is a call to TraceConnectWithoutContext().

This is the error:
Waf: Entering directory
`/home/mzeal/ns-dev/ns-3/ndnSIM-nom-rapid-car2car-master/build'

This is in a fresh install of ns-3.16, ndnSIM, and the car2car extensions
from two days ago in Ubuntu 12.04. The code in V2vTracer looks just like
the code in CarRelayTracer to my naive eye, and I don't know enough about
ns-3 tracing to know where to begin fixing it. Any help will be greatly
appreciated.
