No onError handle by default?

[YamLee]

When subscribed method(method annotated by @subscribe) throw a RuntimeException,RxBus didn't add the onError callback to handle and just throw the exception to App.I think if there is a global method such as RxBus.getInstance().addErrorHandler()or RxBus.getInstance.setDebug(true) provide to client which give client to handle the error or RxBus handle the error by default with release status, that could be better
