DMlibMeshSetSystem()

PetscErrorCode DMlibMeshSetSystem	(	DM	dm,
		libMesh::NonlinearImplicitSystem &	sys
	)

Any functional implementation of the DMlibMesh API must compose the following functions with the DM object.

(See PETSc documentation on PetscObjectComposeFunction(), a polymorphism mechanism.) The following functions are called in PetscNonlinear Solver (others can be called by users): DMlibMeshSetSystem(), DMlibMeshGetSystem()

Any implementation needs to register its creation routine, DMCreate_libMesh, with PETSc using DMRegister().
