All should run through now!

Instead of specifying all of them for all class using IndexSet, those
class now have the index set type as a template parameters.

arrays and allocator. This should eventually be set to std::size_t to
address the entries of the allocated entries.

Currently dd crashes if size_type is size_t. Therefore it is still int
right now.

The EdgeDescriptor ist std::ptrdiff_t.

Thus we can use internal properties during the identification of the
aggregate and save space.
And later on during the galerkin product the visited flag can be
represented by std::vector<bool>.

This should not have any effect if you have just used istl as a sequential
solver.

Now the identification of the excluded vertices
can also be done with custom containers.
