Now the compactvertex and compactface funtions use the importlocal chain so we are sure that all the meaningful data is correctly copied (otherwise ocf stuff will not be copied) On the other hand when using ImportLocal we do not copy pointer based stuff like adjacency and *vertex pointers* that must be terefore copied by hand...
