Document the possible states of connection #120
Description
What are the possible states of connection and how the wsConn and wsConnOK are set in each case?
I tried to make sense of the current code while working on #111. I left some comments in following commits: 386b9ac f871c28 fda2662 a98199a
It would be very helpful to have above question documented.
