/*
  This the starting point of the simulation and experiments.
  The main function will parse the input and parameter settings.
  Creates a highway and set the highway parameters. then bind the events (callbacks)
  to the created controller and designed handlers. Sets the highway start and end time,
  and eventually runs the simulation which is basically running a highway with a controller.
  You can add your functions to controller to create various scenarios.
