Description: Calculates Growing Season Degree Days (GSDD), Growing
        Degree Days (GDD) and the Growing Seasons (GSS) from water
        temperature data. GSSD is a water temperature metric that is a
        useful predictor of age-0 trout size at the beginning of
        winter. It is the accumulated thermal units (in C) during the
        growing season based on the mean daily water temperature
        values. GDD is the GSSD to a particular date.
