[Dune] Another Step towards changing the reference element

[Martin Nolte]

Hallo to all,

yesterday, I added another patch to the gridcheck, that should help grid 
developers to switch to the generic reference element completely.

This one is about the numbering of subentities of a subentity (i.e., method 
subEntity on the reference element). As you all know, the old numbering is not 
consistent with the new one in this point.

Currently, the gridcheck tests whether the grid implements the old numbering 
(which gives us less errors during the transition phase). What I did is to add 
a preprocessor switch to change this behavior. If the test program defines

#define NEW_SUBENTITY_NUMBERING 1

the new subentity numbering is checked.

Now, all we're still missing for a successful transition is a good 
documentation of how this numbering has changed. Maybe someone can provide a 
nice image of the old numbering...

Yours,

Martin
