trigger after Interest is received

The Interest:

The strategy should decide whether and where to forward this Interest.

If the strategy decides to forward this Interest, invoke this->sendInterest one or more times, either now or shortly after
If strategy concludes that this Interest cannot be forwarded, invoke this->rejectPendingInterest so that PIT entry will be deleted shortly

Warning: The strategy must not retain shared_ptr<pit::Entry>, otherwise undefined behavior may occur. However, the strategy is allowed to store weak_ptr<pit::Entry>.

		const Data &	data
	)

trigger before PIT entry is satisfied

This trigger is invoked when an incoming Data satisfies the PIT entry. It can be invoked even if the PIT entry has already been satisfied.

In this base class this method does nothing.

Warning: The strategy must not retain shared_ptr<pit::Entry>, otherwise undefined behavior may occur. However, the strategy is allowed to store weak_ptr<pit::Entry>.

Reimplemented from nfd::fw::Strategy.
