seem to work for the merging of rst syntax (tiger) and coref (mmax2),
the problem with rst is solved
some clean up in tests
pcc11 is no running
added some exceptions
outcommented cycle safety in MergerHandler, it seems, that checking
cycle safety results in wrong data (e.g. converting pcc to relANNIS),
BUT currently, conversion SOMETIMES does not terminate, could this be
solved in cycle safetyness
now pcc11 is convertable except document 2316, but why???
