Gold Challenge
Mayors are people too. An instance of the Mayor type will naturally get nervous whenever its town loses some population due to a Zombie attack. Create a stored instance property on the Mayor type called anxietyLevel. It should be of type Int, and should start out with a default value of 0.
Increment the anxietyLevel property every time a Mayor instance is notified of a Zombie attack.
Last, as a mayor will not want to outwardly display anxiety, mark this property as private.
Verify that this property is not accessible in main.swift.
