[ODE] ODE integrator

[Erin Catto]

ODE uses semi-implicit Euler:

v(t+dt) = v(t) + dt*a(t, p(t), v(t))
p(t+dt) = p(t) + dt*v(t+dt)

Velocities are updated using _old_ accelerations. Positions are updated
using _new_ velocities.

Hi all,
can somebody tell me on which kind of integrator ODE is based 
on?....something like Runge-Kutta IV, Forward Euler or Backward Euler?
Thanks
Bye
Fabio
