!!****  *INIT_SURF_TOPD* - routine to initialize variables needed for coupling with Topmodel
!!
!!    PURPOSE
!!    -------
!!
!!**  METHOD
!!    ------
!!    The routine open and read the namelists NAM_COUPL_TOPD and NAM_TOPD,
!! calculates the number of catchments concerned, the different time step 
!! variables and all the variables nedded for coupling with Topmodel.
