    Procedure @POINTIR
    ------------------

  PTS1 = @POINTIR | 'UNIF' N1                | (MAIL1) ('PINI' PTS2) ...
                  | 'EXCL' N1 'SPHE' R1 (N2) |

     ... ('GERM' | 'AUTO' | ) ;
                 | IGER1  |

    Description :
    ____________

      The @POINTIR procedure draws a random set of points (mesh of POI1)
    distributed uniformaly (UNIF option) or according to a process of
    exclusion (EXCL option) in the domain specified by the mesh MAIL1
    or, if not, in the unit domain. In 2D, the unit domain is a square
    of unit side, centered at the point coordinates (0.5,0.5). In 3D,
    the unit domain is a cube of unit side, centered at the point
    coordinates (0.5,0.5,0.5).

    __________

    'UNIF'    = Key word specifying a uniform distribution of points.

    'EXCL'    = Key word specifying a point distribution generated
                according to a process of "exclusion": each point is
                located at a minimal distance R1 from the others.

    N1        = INTEGER type object: number of points to be generated.
                For the EXCL option, depending on the given distance R1,
                the number of points generated can be lower than N1.

    'SPHE'    = Key word specifying that the area of exclusion around
                the points is a sphere (a circle in 2D) centered on
                these points.

    R1        = FLOTTANT type object: radius of the exclusion area.

    N2        = INTEGER type object: number of iterations for the 
                process of exclusion. By default, N2 is equal to 25*N1.
                
    MAIL1     = MAILLAGE type object (surface in 2D, volume in 3D):
                defines the domain where the points have to be drawn.

    'PINI'    = Key-word which specifies that initial points are given.

    PTS2      = MAILLAGE type object (mesh of POI1) : data points used
                in the process of exclusion to avoid the drawing of
                points at these given sites.
                N.B. : These points are not included in the set of
                       points PTS1 in output of the procedure.

    'GERM'    = Key-word which specifies that a seed is given.

    'AUTO'    = The seed is modified automatically each time the
                procedure is called with this option.

    IGERM1    = INTEGER type object: seed of the random process.

    PTS1      = MAILLAGE type object: mesh of POI1.
