Trying to see whether the euclidean voronoi diagram gives the correct
kleinian diagram. Currently has problems, as not all points are within
the disk.

Draws euclidean voronoi diagram, with lines (mostly) constrained to
within the disk

So... no I can't just use the euclidean voronoi diagram as the voronoi
diagram for the klein disk. Perhaps need to look at the power diagram of
balls
