The exceptions were not printed with a line return anymore, messing up the display. A function to extract the integral and the fractional part of a double has been added. The julian day number calculation (ie how many days since the begining of the year) was numericaly instable (leading to wrong values in an unpredictable way). A data generator that can generate sinusoidal values (for daily or yearly periods) has been added. The potential radiation generator can now handle missing TA and/or RH (of course, reverting to a very simplistic clear sky model, assuming an average reduced precipitable water).
