Hmm, in that case SelectComponentAdapter was probably not meant for
GridFunctions anyway.  But it is of course a good thing to have it for
GridFunctions as well.

Use "diff -u path/to/file.old path/to/file", preferably from the top directory
of the dune-module, or even one directory further up still.  If you checked
out from SVN it is even simpler, just say "svn diff file".  Use "man diff" and
"svn help diff" to get the help for those commands.

Unless there is some other reason you need the "SelectComponentAdaptor", you
probably don't want to invest too much time into it.  Your original approach
basically works, you just have to ignore the error from ParaView.
