/**
* 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.
