[ndnSIM] New forwarding Strategy

[Rajvardhan Deshmukh]

hi Spyros,
I have written a new forwarding strategy and
included following in z-strategy.cpp
const Name 
ZStrategy::STRATEGY_NAME("ndn:/localhost/nfd/strategy/ZStrategy/%FD%00");
NFD_REGISTER_STRATEGY(ZStrategy);

after saving the files z-strategy.cpp and z-strategy.hpp in 
/NFD/daemon/fw
i used ./waf
then included the below method in my main(network simulation)program.

How do i call it in my main program(#include 
"NFD/daemon/fw/z-strategy.hpp") that implements this strategy?
1.
StrategyChoiceHelper::InstallAll("/", 
"/localhost/nfd/strategy/ZStrategy");
--------------------------------------------------------------------------------------------------------------
Problem: Can't test if this is implemented or not

OR

2.
I moved the random-load-balancer-strategy.hpp and 
random-load-balancer-strategy.cpp to /NFD/daemon/fw/
and was able to use 
StrategyChoiceHelper::Install<nfd::fw::RandomLoadBalancerStrategy>(nodes,"/");

I tried using:
StrategyChoiceHelper::Install<nfd::fw::ZStrategy>(nodes,"/");
---------------------------------------------------------------------------------------------------------------
Gives error:
scratch/rvanet.cc.2.o: In function `void 
ns3::ndn::StrategyChoiceHelper::Install<nfd::fw::ZStrategy>(ns3::Ptr<ns3::Node>,

Let me know if further details are required to debug this problem.

Thanks a lot.
