Since the data is coming from NMEA sentences, we are stuck with the
NMEA definitions.  All that I need is names.

I'm thinking maybe:
        wspeedt  -- wind speed true 
        wanglet  -- wind angle true
        wspeeda  -- wind speed apparent
        wanglea  -- wind angle apparent

Little is necessary beyond breathing and eating.
