unsigned int libMesh::MeshTools::Generation::Private::idx	(	const ElemType	type,
		const unsigned int	nx,
		const unsigned int	i,
		const unsigned int	j
	)		[inline]

A useful inline function which replaces the #defines used previously. Not private since this is a namespace, but would be if this were a class. The first one returns the proper node number for 2D elements while the second one returns the node number for 3D elements.
