Detailed Description

Tag part of Track with a weight.

TrackMarkers are used to assign a cost on a span of Track telling how strongly a terminal is dependant on that Track to be accessed. The more Track a terminal crosses, the less the weight is.

The weight is expressed in hundreth (can also be understood as percentage) of dependency over the Track. As example, if a terminal can only be accessed trough one Track is weight on it will be 100.
