more testing, looks good now

n=0 and n=1 are practically useful. n=2 is already a direct
solver. (May I have still something wrong ...)

Ist noch nicht ausführlich getestet (wie alles hier), liefert
aber erst mal ähnliche Ergebnisse wie CG

- supports parallel preconditioners

Guess nobody used them yet :-)

new rules generated from Makefile.am can build the documentation as
well (and with an automagic rerun/bibtex-check :)
