If owner finalizes the round and the coordinator doesn't publish the vote tally, or publishes incorrect data, the funds will be locked in the funding round contract because the recipients will not be able to provide necessary data to claimFunds() (though they can probably brute-force the results if there are only few voters).

This means that owner should wait until coordinator publishes the data and finalize the round only when there's enough evidence that the tally data is correct. To prevent owner from accidentally finalizing the round, we need to require that verifyTotals() is called before finalizing the round.
