The subIndex for higher codim shouldn't be that a big problem.
But the father and hierarchic iterator for higher codim's definitely
a big problem. When we started the definition of the grid interface we
made the decision that the interface should not provide such a
funtionality, because not every grid provides that, so the interface
implementation would be very hard for some grids. But here is another
idea. Why don't we make a default hierarchic iterator by using the
normal hierarchic iterator for codim 0 and the method father, and then
as we have the IdSets (Peter will discribe them on the next meeting) we
can implement a slow default version of this feature and for example
this can be overlaoded by a certain implementation. Also the father
method has to be implemented this way.

What do you think Oli?
