 implements fElement, S2V, fInteractive, MouseListener, MouseMotionListener
Each instance of the class fSquiggle represents a squiggly line.

centerline
 The parametrized curve giving the centerline of the squiggle.

curve
 The parametrized curve whose graph is the squiggle.

from
 The starting point of the squiggle in user coordinates.

height
 The height of the squiggle (maximum distance from the straight line segment
joining the ends) in usr coordinates.

nobumps
 The number of half periods of sin in the squiggle.

normal
 The pseudonormal direction to the centerline curve.

to
 The end point of the squiggle in user coordinates.

fSquiggle()


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

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

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

fSquiggle(double[], double[], double, int)
 Creates a squiggly line with initial point from[]
and final point to[], both in user coordinates.

fSquiggle(S2V, S2V, double, double, double, int)
 Creates the squiggly line with centerline and pseudonormal given by
the first two arguments, parameter range for the centerline and pseudonormal given
by the third and fourth arguments, height given by the fifth argument and number of bumps given
by the final argument.

fSquiggle(S2V, S2V, double, int)
 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.

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.
