Document soft AP device command flow

I'm imagining this to simply be a code comment somewhere, but it could be in the README or another piece of documentation. It would help newcomers to the code get oriented if there were a list of the typical flow through soft AP in terms of the commands issued to the device.

From a conversation with @idokleinman, here's the current state of things:

device-id -> public-key -> set -> scan-ap -> configure-ap -> connect-ap

Actually there's lots of internal code flow that happens in Soft AP, also in SDK. I am not sure README is a suitable place for documenting that. I can add few lines to the header or implementation file of SparkSetupCommManager class probably
