Runge–Kutta method RK4 for second order differential equations

Differential equations of the type: y'' = f(x, y, y')

Due to the implementation with pointers to arrays, all of the variables are stored in arrays.

Console Output:

----------------------------
x:      0.000
y:      0.000
yd:     4.000
ydd:    -8.000
