Shifted the query type condition into setquerytype, so it's no longer
stored as a string. Also did some rejigging to get the tabs consistent,
and added some comments for a few less obvious areas of code.

\foreach \x in {-2,-1.4,-0.5,0,0.8,1.3,1.8} {
  \draw (\x,-0.2) -- (\x,0.2); 
}          
\input track.tikz
