    public interface ProgressPipe<P,​D_OUT,​F_OUT,​P_OUT>
    A pipe invoked when the Promise publishes intermediate results while it is still in the state Promise.State.PENDING. Pipes allow to start a new Deferred and any state change or update invoked on the new Deferred is piped to the outer Promise. This allows to chain asynchronous calls or convert a rejection into resolve or vice versa.
