class GeomCurve from GeomToIGES inherits GeomEntity from GeomToIGES

    ---Purpose: This class implements the transfer of the Curve Entity from Geom
    --          To IGES. These can be :
    --          Curve
    --            . BoundedCurve
    --               * BSplineCurve
    --               * BezierCurve
    --               * TrimmedCurve
    --            . Conic     
    --               * Circle
    --               * Ellipse
    --               * Hyperbloa
    --               * Line
    --               * Parabola
    --            . OffsetCurve
