Not quite. I just didn't had the time today to add the points that 
should be realized within release 1.0 from the Freiburg point of view.
Tomorrow I'll add them to the tex file in the cvs that Peter created.

I might forgot some points but the main things are:

1) Entities for higher codims in Yasp- and UGGrid (Faces and Edges)
2) unified communication for parallel grids (mainly work to do in ALUGrid)
3) backup and restore for Grids (mainly work in UGGrid, for all other 
it's implemented)
4) Unified constructor for all grid was a point, but it seems like that 
only Freiburg agrees with that.

I'll add these points to the list.

Regards
