    Description :
    _____________

    The ZIGZAG procedure enables the building of a line by a sequence
    of strait (D) or curve [(S,R) or (A,R)] parts.


    Contents :
    __________

    POIN0   : initial point of the line (POINT type).

    V1      : tangential vector of the line from POIN0 (POINT type).

    V2      : second vector (POINT type) essential for the definition
              of the plan containing the line. This plan is oriented by
              the vector product N = V1 ^ V2.

    N1      : wished number of element (ENTIER type).

    DENS1 | : initial and final point densities (FLOTTANT type).
    DENS2 |

    LONG1   : length of the strait part to create (FLOTTANT type).

    LONG2   : length of the curve part to create (FLOTTANT type)
              (positive measurment in the normal direction N).

    ANGL1   : angle of the curve part (FLOTTANT type)
              (positive measurment in the normal direction N).

    RAY1    : radius of the curve part (FLOTTANT type).

    GEO1    : created line (MAILLAGE type).


    Note :
    ______
     1/. The first parameter must be POIN0, followed by V1 and V2.
     2/. Each elementary line has a node at its extremities.
     3/. If N1 is given, N1 elements with more or less the same
         length will be created.
     4/. If the densities DEN1 and DEN2 are given, the size of the
         elements will be computed taking these values into account.
