[ndnSIM] ndnSIM Digest, New forwarding strategy

[Spyridon (Spyros) Mastorakis]

Hi,

have you tried to register your strategy like this?

https://github.com/named-data-ndnSIM/NFD/blob/38111cde9bab698f6eaf1a9d430130c2cbb3eca4/daemon/fw/multicast-strategy.cpp#L32-L33 <https://github.com/named-data-ndnSIM/NFD/blob/38111cde9bab698f6eaf1a9d430130c2cbb3eca4/daemon/fw/multicast-strategy.cpp#L32-L33>

Thanks,

Spyridon (Spyros) Mastorakis
