start work on dew-heater board & remove root dir DESCRIPTION
more WizFi updates....

After further research, I'm not convinced the WizFi is the way to go.
Most likely will need to replace it with something else if I want
to support serial ports.  Probably should move the serial ports
to a daughter board.
