Verify the transaction matches the conditions from this clause. For example, a "no zero amount output" clause would check each of the output states that it applies to, looking for a zero amount, and throw IllegalStateException if any matched.
verifyNetCommand fun verifyNetCommand(inputs: List<State<P>>, outputs: List<State<P>>, command: AuthenticatedObject<Net>, netState: NetState<P>): Unit

Verify a netting command. This handles both close-out and payment netting.
