Detailed Description

DakotaROLObjectiveHess is derived from DakotaROLObjectiveGrad. It implements overrides of ROL member functions to provide a Dakota-specific implementation of a Hessian-vector product. This separate class is needed (rather than putting the product into DakotaROLObjective) because logic in ROL does not always protect against calling the Hessian-vector product in cases where there is not actually a Hessian provided.
