Update models/Application_examples/Autonomous_Car.mp, models/Application_examples/Knapsack_Weight_Limit.mp, models/Application_examples/Spent_Fuel_Cooling_and_Cleanup.mp, models/Example29_Gantt_Chart.mp files

Shrunk borders on examples 25-38 and application examples "Application Process," "Aspect_Oriented_Paradigm," and "Authentication."

Added section title headers to every file, and moved references to the correct location within these sections.
