-Then, to determine who's won the raffle (it's probably you!), resolve the raffle by calling the `resolve` function. If you do this fast enough (or if you set a really high raffle duration), you will get an error with code `0 = ERaffleNotResolvableYet`. This is good; it means that the raffle is working as intended! Wait a little longer and try again. (Or create a new raffle that has a shorter duration.)
