        Create a Behavior for a persistent actor.

        Parameters:
        persistenceId - stable unique identifier for the event sourced behavior
        emptyState - the intial state for the entity before any events have been processed
        commandHandler - map commands to effects e.g. persisting events, replying to commands
        eventHandler - compute the new state given the current state when an event has been persisted
        Returns:
        (undocumented)

        Create a Behavior for a persistent actor that is enforcing that replies to commands are not forgotten. Then there will be compilation errors if the returned effect isn't a ReplyEffect, which can be created with Effect.reply, Effect.noReply, EffectBuilder.thenReply, or EffectBuilder.thenNoReply.
        Parameters:
        persistenceId - (undocumented)
        emptyState - (undocumented)
