>
> The ContinuousOutputModel class allows to store the evolution of the state of
> an ODE system throughout integration. It aims to provides at a global level
> all the information that is available at local level in step handlers. It
> does so by storing the step interpolators as integration is performed, and
> delegate data retrieval to the interpolator matching the time step.
> However, there is a missing part: step interpolators do provide access to the
> derivatives of the state, whereas ContinuousOutputModel does not. A
> getInterpolatedDerivatives method should be added, matching the method with
> the same name in StepInterpolator.
