/** \brief A ModelEvaluator which wraps the application ModelEvaluator.
 *
 *  The WrapperModelEvaluator takes a state, \f$x\f$, computes time
 *  derivative(s), \f$\dot{x}\f$ and/or \f$\ddot{x}\f$, from the
 *  implicit stepper (StepperImplicit) and calls the application
 *  ModelEvaluator to determine its residual, \f$\mathcal{F}(x)\f$,
 *  which is suitable for the nonlinear solve.
