To refer to a node, we must know its number, which can be computed as
in the following example:
<pre>
obs = {'LeftClrSens', 'RightClrSens', 'TurnSignalSens', 'XdotSens', 'YdotSens', 'FYdotDiffSens', ...
      'FclrSens', 'BXdotSens', 'BclrSens', 'BYdotDiffSens'};
for i=1:length(obs)
  onodes(i) = strmatch(obs{i}, names);
end
onodes = sort(onodes);
</pre>
(We sort the onodes since mos
