//This script handles how risk of infection for a player/ gameobject increases with time. We know that being in an enclosed space
//with other individuals for a sustained period increases the risk of infection.

//This risk factor hinges on risk vectors, provided below in our model, as well as the number of infected people in the space,
//which we can pull from our CalculateInfected script.
