> Sometimes, very fast computation of only a few steps of an ODE integrators are needed
and embedded in much larger loops. Setting up a full-blown integrators with all its bells
and whistles is cumbersome in this case where only the final state is desired.
> A stripped-down version of the ODE integrator using only the Butcher arrays from Runge-Kutta
integrators would be nice.
