Matrix colorings (MatColoring), orderings (MatOrdering), partitionings (MatPartitioning), and coarsening (MatCoarsen)

These tools compute reorderings (MatOrdering) (for sparse matrix factorizations), colorings (MatColoring) (for computing Jacobians via finite differences), partitionings (MatPartitioning) (for parallel decomposition of data), and coarsening (MatCoarsen) (for algebraic multigrid methods).
