This method is called only if you implemented the
IwodSSHNotify interface in your application, and the
wodSSH.Notification
property has received a reference to the instance of your
implementation.
The StateChange notification method is called each time
wodSSH's internal state changes. Initially, it is set to
Disconnected. Once you initiate new
connection, it will change to Connecting, etc..
Using this notification method you can see if there is
something happening with wodSSH, or it is idle and waiting
for your commands.
You can determine the current state using the State property.
