EventSink<T> class

A Sink that supports adding errors.

This makes it suitable for capturing the results of asynchronous computations, which can complete with a value or an error.

The EventSink has been designed to handle asynchronous events from Streams. See, for example, Stream.eventTransformed which uses EventSinks to transform events.
