## RungeKuttaSpringImplementation.m
// Evaluates one tick of a spring using the Runge-Kutta Algorithm.
// This is generally a bit mathy, here is a reasonable intro for those interested:
// http://gafferongames.com/game-physics/integration-basics/
// (double)stepSize: the duration between steps. This should be around 1/60th of a second. Values too large will not work as the spring adjusts itself over time based on previous values, so if values are larger than 1/60th of a second this method should be called for each whole 1/60th of a second segment plus the remainder.

// external variables
// (double) _curT: How far along the spring the current value is, 0 being start and 1 being end. Because this is a spring that value will go beyond 1 and then back below 1 etc, as it 'springs'.
// (double) _tVelocity: the current velocity of the spring.
// (BOOL)   _stopSpring: indicates the spring has settled to minimum amount and should be considered the last 'tick'
