  /**
   * This spring model is based off of a damped harmonic oscillator
   * (https://en.wikipedia.org/wiki/Harmonic_oscillator#Damped_harmonic_oscillator).
   *
   * We use the closed form of the second order differential equation:
   *
   * x'' + (2ζ⍵_0)x' + ⍵^2x = 0
   *
   * where
   *    ⍵_0 = √(k / m) (undamped angular frequency of the oscillator),
   *    ζ = c / 2√mk (damping ratio),
   *    c = damping constant
   *    k = stiffness
   *    m = mass
   *
   * The derivation of the closed form is described in detail here:
   * http://planetmath.org/sites/default/files/texpdf/39745.pdf
   *
   * This algorithm happens to match the algorithm used by CASpringAnimation,
   * a QuartzCore (iOS) API that creates spring animations.
