WiggleInterpolator(amplitude: Double, desiredPeriod: Double, baseInterpolator: HeadingInterpolator = TangentInterpolator())
Heading interpolator that wraps another interpolator and adds sinusoidal oscillations ("wiggles") while preserving continuity. More specifically, the wiggle function is composed of a sine wave with a quintic spline on either end.
amplitude - amplitude of the wiggle oscillations
desiredPeriod - period fo the wiggle oscillations
baseInterpolator - base interpolator to add oscillations to (e.g., oscillations relative to the tangent)
