Interface Promisable<C extends FlowContext>

Type Parameters:
C - the type of the context shared between tasks
All Known Subinterfaces:
Repeat<C>, Sequence<C>
public interface Promisable<C extends FlowContext>
An interface to use the promise when executing asynchronous tasks.

Error Handling
When using the methods in this interface, errors in tasks are propagated to the closest catch handler. This is different from the methods in Subscription that catches errors in tasks and stores them in the context.
