Detailed Description

ModelEvaluator adaptor that implements the stochastic Galerkin residual and Jacobian computations using quadrature.

This class provides a ModelEvaluator implementation to adapt a non-SG capable ModelEvaluator to one that can be used by Stokhos::SGModelEvaluator. It does so be implementing the SG residual and Jacobian calculations by sampling a multi-point ModelEvaluator at a set of quadrature points.
