## Detailed Description

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