New tests for breaking a track
Can now break lone tracks

Added an equals method for a track that only considers the points
of each track. Does not distinguish between order of points.
Tracks in 1 intersection can be broken

Added test for track in 2 intersections, not working at the moment
Tracks with 2 intersections can now be broken

The track constructor now uses the new point constructor
Can now break tracks using the Map Creator
