! Purpose: average cell centred values around a grid node.
!
! Description: there are the following functions:
!              - Aver    = averages one variable
!              - AverDiv = divides variable 1 by variable 2 and
!                          conducts the averaging.
!
! Input: 
!
! Output: Aver    = average value
!         AverDiv = average value divided by second variable.
!
! Notes: simple arithmetical averaging is used.
