public class RungeKuttaK4
extends Algorithm
A class that implements the Runge-Kutta Classic 4th Order Algorithm:

y_n = y_{n - 1} + ( K1 + 2K2 + 2K3 + K4 ) / 6

where,

K1 = h * f( t_{n - 1}, y_{n - 1} )
K2 = h * f( t_{n - 1} + h / 2, y_{n - 1} + K1 / 2 )
K3 = h * f( t_{n - 1} + h / 2, y_{n - 1} + K2 / 2 )
K4 = h * f( t_{n - 1} + h, y_{n - 1} + K3 )
