This demo includes four graphical display windows.
Three of the windows graph the arclength s(t), the curvature k(t), and
the torsion τ(t) used to determine the curve X(t).
The fourth window graphs the Taylor approximation of the curve X(t) colored according to torsion
that would result from s(t), k(t), and τ(t), with starting point (0, 0,
You can change t0, s(t), k(t), τ(t), and the starting point,
"Start", in the control
