* @param {PartialObserver|Function} observerOrNext (optional) either an observer defining all functions to be called,* or the first of three possible handlers,which is the handler for each value emitted from the observable.
* @param {Function} error (optional) a handler for a terminal event resulting from an error. If no error handler is provided,* the error will be thrown as unhandled
* @param {Function} complete (optional) a handler for a terminal event resulting from successful completion.
* @return {ISubscription} a subscription reference to the registered handlers
