/**
The smart routing strategy relies purely on manipulating costs and lets the smart routing algorithm pick the terminator.
It increases costs by a small amount when a new circuit uses the terminator and drops it back down when the circuit
closes. It also increases the cost whenever a dial fails and decreases it whenever a dial succeeds. Dial successes
will only reduce costs by the amount that failures have previously increased it.
