[Mattias Bengtsson <mattiasb src gnome org>]

    Add Route classes
    
    A Route is an array of Route.Segment and metadata.
    
    A Route.Segment is a lineString (an array of coordinates) that forms
    the road until the next segment, a human readable description of how to
    continue onto that road and some other metadata.
