Example usage:

[[AFNetworkReachabilityManager sharedManager].rac_reachabilityStatusChangeSignal subscribeNext:^(NSNumber *status) {
    AFNetworkReachabilityStatus status = [status integerValue];
    UALog(@"Reachability Status (1): %d", status);
    // Do something
}];

Subscribing to the signal will automatically start monitoring reachability status.
