what's the reason for having a class that emulates networkingPrivate methods?
For testing?

The long term goal is to move all Settings to one or more component extensions.
During the long transition, we want to develop Settings UI code that can be
integrated into other apps (e.g. Kiosk apps) to allow some level of network
configuration UI without running Chrome.
This class provides that transition layer. The idea is that the JS code can be
copied, with the simple addition of 'networkConfig = chrome.networkingPrivate'.

I see. So the idea is for the two hooks (the networkingPrivate API
implementation and network_config.js) to use the same backend (i.e.
NetworkHandler)? I'm not super familiar with the networkingPrivate
implementation but it seems to me that the two APIs can pretty much share their
entire C++ back end. Sorry if this doesn't make sense, I'm just trying to make
sense of it.

+
+  DISALLOW_COPY_AND_ASSIGN(NetworkConfigMessageHandler);
