* SGInverseModelEvaluator is an implementation of EpetraExt::ModelEvaluator
* that does the inverse of SGModelEvalutor, namely it takes SG versions of
* the p InArgs and g and dg/dp OutArgs, and converts them to block vectors
* that are passed to the underlying model evaluator. This allows block
* nonlinear problems to appear to SG problems.
