NOX Petsc support.
NOX provides support for PETSc data structures through concrete implementations of the NOX::Abstract::Group and NOX::Abstract::Vector. A SharedJacobian class exists which for now simply wraps a PETSc matrix used as the Jacobian. Future enhancements may include generalizing this to an operator supporting the finite-difference and matrix-free capabilities provided in PETSc.
An Interface class provides callbacks to the application needed for function (residual) evaluations and possibly matrix (Jacobian) fills.
