Ichthyostega 155bf95ce5 Doxygen: magically insert a reference to the test class
this bit of Sed magic relies on the fact that we happen to write
the almost correct class name of a test into the header comment.

HOWTO:
for F in $(find tests -type f \( -name '*.cpp' \)  -exec egrep -q '§§TODO§§' {} \; -print);
  do sed -r -i -e'
    2          {h;x;s/\s+(.+)\(Test\).*$/\\ref \1_test/;x};
    /§§TODO§§/ {s/§§TODO§§//;G;s/\n//}'
    $F;
done
