Segment ()=default  
A Segment represents a bundle of adjacent Lanes which share a continuously traversable road surface.
Every LanePosition on a given Lane of a Segment has a corresponding LanePosition on each other Lane, all with the same heightabovesurface h, that all map to the same GeoPoint in 3space.
Segments are grouped by Junction.

inline 
Returns the persistent identifier.
Returns the Lane indexed by index
.
The indexing order is meaningful; numerically adjacent indices correspond to geometrically adjacent Lanes. Indices increase "to the left", i.e., in the direction of increasing r
coordinate.
index
must be >= 0 and < num_lanes().

inline 
Returns the number of Lanes contained in this Segment.
Return value is nonnegative.
