[ndnSIM] New forwarding Strategy

[Spyridon (Spyros) Mastorakis]

Hi,

use the strategy choice helper. If there is not such a strategy implemented, NFD will log an appropriate error message:

https://github.com/named-data-ndnSIM/NFD/blob/NFD-0.5.0-30-g934f505-ndnSIM/daemon/mgmt/strategy-choice-manager.cpp#L58-L59

Enable the “StrategyChoiceManager" logging component to be able to see that.

Thanks,

Spyridon (Spyros) Mastorakis
