    Request Observable to start streaming data.
    This is a "factory method" and can be called multiple times, each time starting a new Subscription.
    
    Each Subscription will work for only a single Observer.
    
    If the Observable rejects the subscription attempt or otherwise fails it will signal the error via Observer.onError(java.lang.Throwable).
    
    Parameters:
    
    observer - the Observer that will consume signals from this Observable
