Returns two observables which split the observations of the source by the given function. The first will trigger observations for which the splitter returns Choice1Of2. The second will trigger observations y for which the splitter returns Choice2Of2. The splitter is executed once for each subscribed observer. Both also propagate error observations arising from the source and each completes when the source completes.
