Before adding detailed documentation for this and before
starting to advertise this I'd like to know if these
additions/changes are OK for you.</pre>

I think that in any case we still need a general disclaimer stating
something like<br>
"this is a technology preview -- no API is fixed yet -- may eat your
cat -- follow the mailinglist"<br>

<pre wrap="">Finally, I have also started to write prose explaining how the stokes-taylorhood.cc example
works. I wrote that for the book, and it actually describes a separate implementation
which uses MultiTypeBlockMatrices for the linear algebra. If I find the time I may
factor out that text into a separate document and upload it to dune-functions itself.

It would be very nice, if you could add this example to
dune-functions. I'd really like to have A and B working
for this and I have the impression that it mostly is,
once you add support for multi-type containers to the
HierarchicVectorWrapper or provide an alternative wrapper.
But in some places I'm not sure.</pre>

This is where I am currently stuck. I'd like to handle the VTK
output in the way it is done in stokes-taylorhood.cc.<br>
But there, the expression <br>
<br>
Functions::hierarchicVector(x)<br>
<br>
shows up, and in my case x is a MultiTypeBlockVector. To be honest
I didn't try it yet, but I suppose<br>
I need to generalize hierarchicVector to also function with a
MTBVector?<br>

The reason for this is, that these A and B are a good
indicator if the interface is rich enough/usable in
such cases. If you can't implement A and B, we may
have to adjust the interface. And this should be done
as soon as possible.
Best,
Carsten
