The contour functions has sommewhere (I think in .../main/plot3d.c) a maximum
number of line segments that is set using a define. The contour line in my data
too long for this and therefore not correct analysed (I get the message
'contour(): circular/long seglist -- bug.report()!'). Since I can't analyse my
data right now, it's mybe better to give the maximum seg-number as an option ?!
