15! Description:
16! ------------
17! Calculation of user-defined statistics, i.e. horizontally averaged profiles
18! and time series.
19! This routine is called for every statistic region sr defined by the user,
20! but at least for the region "total domain" (sr=0).
21! See section 3.5.4 on how to define, calculate, and output user defined
22! quantities.
