 public fSquiggle(double from[],
                  double to[])

Creates a squiggly line with initial point from[] and final point to[], both in user coordinates.

 public fSquiggle(double x1,
                  double y1,
                  double x2,
                  double y2)

Creates a squiggly line with initial point (x1,y1) and final point (x2,y2), both in user coordinates.

 public fSquiggle(double from[],
                  double to[],
                  double height,
                  int nobumps)

Creates a squiggly line with initial point from[] and final point to[], both in user coordinates. The height and number of bumps are given by the last two arguments.

                  double y1,
                  double x2,
                  double y2,
                  double height,
                  int nobumps)

Creates a squiggly line with initial point (x1,y1) and final point (x2,y2), both in user coordinates. The height and number of bumps are given by the last two arguments.

 public fSquiggle(S2V centerline,
                  S2V normal,
                  double height,
                  int nobumps)

Creates the squiggly line with centerline and pseudonormal given by the first two arguments, height given by the third argument and number of bumps given by the final argument. The squiggly line consist of the curve

curve(t) = centerline(t) + height * Math.sin(Math.PI*nobumps*t) * normal(t) ;

with parameter value running from 0 to 1. Note that curve(t), centerline(t) and normal(t) are all two component arrays.

The squiggly line consist of the curve

curve(t) = centerline((1-t)*tmin+t*tmax) + height * Math.sin(Math.PI*nobumps*t) * normal((1-t)*tmin+t*tmax) ;

with parameter value running from 0 to 1. Note that curve(t), centerline(t) and normal(t) are all two component arrays.

In the latter case, normal is a unit vector perpendicular to the vector joining from and to.
