    Returns the number of intersections between this curve and a line segment defined by the two specified points.
    This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.
    
    Specified by:
    
    getLineSegmentIntersectionCount in interface ILcdCurve
    
    Parameters:
