From c5cf806f8276786017bd69e61a2db1c014ec52ce Mon Sep 17 00:00:00 2001
From: Torbjörn Andersson
Date: Tue, 21 Feb 2006 10:22:37 +0000
Subject: Removed the "extra bars/nodes" code, since nothing ever added the
 extra bars or nodes.

Removed the path-plotting debugging code, since the line-drawing function has
been a stub for the past few years, as far as I can tell.

Similar code was removed from the BS2 router long ago, so this could be a first
tiny step towards bringing them together.
