1. How do move Tokens through the two legs of the Fork?
2. What API do you use to declare a unique Token for each leg?
3. What API do you use to advance each token in each leg ?
4. What API do you use to check that both legs have completed?
A Code example would be really appreciated. Figure 7.1 - Auction Process would be an ideal example.
A fork automatically creates child tokens.
A join automatically checks that both legs have completed.
You don't have to do it by yourself.
