Detailed Description
Shared Jacobian for NOX::Petsc::Group objects.
Due to the size of the Jacobian, we cannot afford to have multiple copies. Instead we implement a shared Jacobian that all groups use.
NOTE: An additional matrix is included with the SharedJacobian in anticipation of having a separate Matrix for the Jacobian and the Preconditioner. This option will be available in the future.
