Electron sample code for fault tolerance and problem debugging

Most of the time the Electron just works, happily connecting and disconnecting from the cellular network and all is good. Except once in a while, some devices have a hard time getting reconnected. Disconnecting the battery and power usually solves the problem, but that can be a pain for remote devices. This experiment is some code that might help recover from this situation automatically, and also log some data to better figure out what’s actually happening, so if it’s a bug, it can just be fix…

There is also an open issue on GitHub that deals with the problem (which is milestoned for 0.6.0, so you could checkout the pre-release 0.6.0-rc.1)
