[ndnSIM] Linking error

[chavoosh ghasemi]

Yes, it is included ("*ndn-load-balancer/random-load-balancer-strategy.hpp*").
To clarify the problem, even if I just copy and paste *ndn-l*
*oad-balancer.cpp* example and rename it, it won't work. Something is wrong
with linking part and I guess maybe I need to add the name of new examples
to waf/makefile. If you can, please test it on your own machine and let me
know if you had any problem.
