[Dune] HierarchicIndexSet.

Hello Oli,

As I described before, the HierarchicIndexSet is the LocalIdSet plus a
size method. This means in addition to the LocalIdSet (IdTye of
LocalIdSet is int) you can ask this class, what the highest used index
+1 is, i.e. the size. This index set is not consecutive but persistent.
The implementation of AlbertaGrid and ALUGrid will return the same index
for an entity as the local id for that entity is.

For the classes exist a documentation that describe the methods.
The HierarchicIndexSet implement the interface of the Dune::IndexSet.
