Construct NtpClock assuming network is available

That's a good point. It's because I haven't needed to use the WiFi for anything except for NTP time so far. Do you have some suggestions? Maybe another constructor that does not require the setup() method to be called? I'm happy to look at well-crafted pull requests.

Thanks. I am thinking about constructor with no parameters; other operations should check that Wi-Fi is connected before interacting with the network. With setup() or not, it's worth doing this anyway, because Wi-Fi connection can go away any time. Perhaps, a constructor could take an optional WiFiUDP object, for projects which have already allocated it for their own use.

I'll try to submit something along these lines, but no hard promise :-)

I made some tweaks and fixes, and pushed them to the develop branch. Things look good.

I'll leave this issue open for now, until I get back from vacation. (Will be unable to respond for a couple of weeks.)

Thanks.
