! This modules deals with all aspects of testfield fields; if no
! testfield fields are invoked, a corresponding replacement dummy
! routine is used instead which absorbs all the calls to the
! testfield relevant subroutines listed in here.
!
! NOTE: since the fall of 2007 we have been using the routine
! testfield_z.f90, not this one! For more information, please
! contact Axel Brandenburg <brandenb@nordita.org>
