!!****  *WRITE_DIACHRO* - Ecriture d'un enregistrement dans un fichier

!!
!!    PURPOSE
!!    -------
!
!
!!**  METHOD
!!    ------
!!      En fait pour un groupe donne HGROUP, on ecrit systematiquement
!       plusieurs enregistrements :
!       - 1: HGROUP.TYPE          (type d'informations a enregistrer)
!       - 2: HGROUP.DIM           (dimensions de toutes les matrices a
!                                  enregistrer)
!       - 3: HGROUP.TITRE         (Nom des processus)
!       - 4: HGROUP.UNITE         (Unites pour chaque processus)
!       - 5: HGROUP.COMMENT       (Champ commentaire pour chaque processus)
!       - 6: HGROUP.TRAJT         (Temps)
!       - 7: HGROUP.PROCx         (Champ traite . 1 enr./ 1 processus)
!       - 8: HGROUP.DATIM         (Les differentes dates du modele)
!       et pour certains types d'informations on enregistre egalement
!       des coordonnees (HGROUP.TRAJX, HGROUP.TRAJY, HGROUP.TRAJZ)

!!    MODIFICATIONS
!!    -------------
!!      Original       08/01/96
!!      Updated   PM
!!      Modification (N. Asencio) 18/06/99  : the two first dimensions of PMASK
!!                   are linked to the horizontal grid, FMWRIT is called with 'XY' argument.
!!                   In standard configuration of the budgets, the mask is written once
!!                   outside this routine with FMWRIT call. Its record name is 'MASK_nnnn.MASK'
!!                   So optional PMASK is not used .
!!      Modification (J. Duron)   24/06/99  : add logical GPACK to disable the pack option,
!!                                            add the initialization of the dimensions of
!!                                          MASK array in MASK case with write outside the
!!                                          routine.
!!      J.Escobar       02/10/2015 modif for JPHEXT(JPVEXT) variable
!!      D.Gazen+ G.Delautier 06/2016 modif for ncl files
!!      P. Wautelet     09/06/2017: name of the variable added to the name of the written field
!!                                  and better comment (true comment + units)
!!  Philippe Wautelet: 05/2016-04/2018: new data structures and calls for I/O
!  P. Wautelet 13/09/2019: budget: simplify and modernize date/time management
!  P. Wautelet 13/09/2019: remove never used PMASK optional dummy-argument
!  P. Wautelet 28/08/2020: remove TPLUOUTDIA dummy argument
!  P. Wautelet 09/10/2020: use new data type tpfields
!  P. Wautelet 08/12/2020: merge budgets terms with different nbutshift in same group variables
!  P. Wautelet 03/03/2021: add tbudiachrometadata type (useful to pass more information to Write_diachro)
!  P. Wautelet 11/03/2021: remove ptrajx/y/z optional dummy arguments of Write_diachro
!                          + get the trajectory data for LFI files differently
