 There are a few key things to note here:
-1. The constants class will need to inherit from UnitySimulationScenarioConstants to be compatible with the Run in Unity Simulation window. Deriving from UnitySimulationScenarioConstants will add a few key properties to the constants class that are needed to coordinate a Unity Simulation run.
-2. Make sure to include the [Serializable] attribute on a constant class. This will ensure that the constants can be manipulated from the Unity inspector.
-3. A scenario class's Serialize() and Deserialized() methods can be overriden to implement custom serialization strategies.
