A TRoute describes a sequence of links and nodes, together making up a route between 2 nodes or 2 locations:


If there are one less links than nodes: Between 2 nodes (and percent1=percent2=0)

If there are one less nodes than links: Between 2 locations


TRoute = record

 nodes: TIntegerArray

 links: TIntegerArray

 percent1,percent2: TPercent



If a link number is negative it is travelled in the reverse direction.
