     Description :
     _____________

     Creates a CHPOINT defined on a subset of points (SPG underlying 
     spaces) defined on the given MODEL object or on the DOMAINE TABLE.
                                

     Notes :
     _______

      MOD1 : MMODEL object subtype 'NAVIER_STOKES' or 'DARCY'

      TAB1 : TABLE  object subtype 'DOMAINE'

      MOT1 : | 'SCAL' |   MOT2 : | 'SOMMET'   |
             | 'VECT' |          | 'FACE'     |
                                 | 'CENTRE'   |
                                 | 'CENTREP1' |
                                 | 'MSOMMET'  |

      'VERIF' : Keyword in order to have an echo of the initialized
                components.

      'COMP'  : Keyword in order to change names of components
                MOTi : component names

      FLOT1   : CHPOINT initial value (FLOTTANT type) if MOT1 = 'SCAL'

      VEC1    : CHPOINT initial value (VECTEUR type) if MOT1 = 'VECT'

      CHPO2   : CHPOINTs used to initialize CHPO1 
       ...      The values of CHPOn defined on the SPG will eventually
      CHPOn     override FLOT1 or VEC1 and the values of CHPOn-1

      CHPO1   : resulting CHPOINT
 
     Comments :
     __________

 1/  The CHPOINT is a set of values associated to points. One can
     associate at each point one or several values (SCAL VECT etc..)
     The fields represented by a CHPOINT can be either continuous or
     discontinuous or for a vector field they can be represented by
     the flux. We choose in the frame of CFD to use the same objects
     type 'CHPOINT'. There are four points subsets which are SOMMET
     (vertices) FACE CENTRE (cell center) CENTREP1 (3 cells points
     defining a linear pressure in 2D, 4 cells points in 3D).
     The CHPOINTs SPG (underlying spaces) are taken by KCHT among the
     list above. The SPG are checked with the model.

 2/  We can use KCHT to affect the right SPG to a CHPOINT.
