    Description :
    _____________
 
    The PLUS operator creates a new object and either translates the geometrical
    support of an operand from a vector, or transforms it according to the
    displacement field (CHPOINT type), depending on the last operand type.
    In case of a CHPOINT, the image points of its support are built from
    the values of the components 'UX' 'UY' ('UZ') or 'UR' 'UZ' at each point.
    When the operator applies simultaneously to several operands, the
    elementary geometrical supports are only transformed once.

                               | CHPO1 
 
        NOBJ1   ... NOBJN  = OBJ1 ...  OBJN  PLUS |  VEC1    ;
                                                  |  CHPO1

         OBJ1 : POINT or MAILLAGE or CHPOINT or MCHAML or MMODEL type 
                the RIGIDITE type is allowed for a translation from VEC1
                but forbidden for the transformation from CHPO1
 
      OBJ1 ... OBJN : see OBJ1

         VEC1 :  POINT type

        CHPO1 :  CHPOINT type
  
         OBJ2 : result of the same type than OBJ1

    NOBJ1 ... NOBN : results of the same type than OBJ1 ... OBJN
