/** \brief Specialization of IMEX-Part ME for "combined" FSA method.
 *
 * This specializes the implementation of several parts of
 * WrapperModelEvaluatorPairPartIMEX_Basic for forward-sensitivity analysis
 * with CombinedForwardSensitivityModelEvaluator.  It deals with the product
 * structure of the sensitivity solution vectors and incorporates the
 * sensitivity of the implicit term with respect to the explicit-only vector.
