CCC  Purpose :
CCC  ---------
CCC     output of passive tracer : additional 2D and 3D arrays
CCC
CCC
CC   Method :
CC   -------
CC
CC	At the beginning of the first time step (nit000), define all
CC	the NETCDF files and fields for concentration of passive tracer
CC
CC      At each time step call histdef to compute the mean if necessary
CC	Each nwrite time step, output the instantaneous or mean fields
CC
CC	IF kindic <0, output of fields before the model interruption.
CC      IF kindic =0, time step loop
CC      IF kindic >0, output of fields before the time step loop

CC   Input :
CC   -----
CC      argument
CC              kt              : time step
CC		kindic		: indicator of abnormal termination
CC      COMMON
CC            /comcoh/          : orthogonal curvilinear coordinates
CC                                and scale factors
CC            /comask/          : masks, bathymetry
CC            /cottrc/          : passive tracers fields (before,now
CC                                  ,after)
CC            /citcdf/		: NETCDF variables
CC
CC   Output :
CC   ------
CC      file
CC              "clhstnam" files : one for concentration, one for
CC                                 aditional 2D and 3D arrays
