 - Renaming of variables and subroutines to make everything clearer. In particular, the suffixes: '_avg' = average, '_start' = PCM start file, '_dev' = deviation, '_ini' or '0' = initial, '_dyn' = dynamical grid, '_timeseries' = daily average of last PCM year.
 - Cosmetic cleanings for readability.
