#   ---------------------------------- calculate time average of x and 
#                                      temporal variance x"x".
#
#   Usage: meanvar x  tx txp2 [xp]
#          Input file:
#            x    ($1) = gridded (multi-level) data. 
#          Output files:
#            tx   ($2) = time average of x,
#            txp2 ($3) = time average of (x-tx)**2,
#            xp   ($4) = (optional) deviations from the time mean (x-tx).
