 /*
  * The purpose of this application is to support development of the RoadManager by visualizing the road network and moving objects on top.
  * Bascially it loads an OpenDRIVE file, and optionally a corresponding 3D model, and then populate vehicles at specified density. The 
  * vehicles will simply follow it's lane until a potential junction where the choice of route is randomized.
  *
  * The application can be used both to debug the RoadManager and to check OpenDRIVE files, e.g. w.r.t. gemoetry, lanes and connectivity.
  *
  * New road/track segments is indicated by a yellow large dot. Geometry segments within a road are indicated by red dots.
  * Red line is the reference lane, blue lines shows drivable lanes. Non-drivable lanes are currently not indicated.
