/*
* Calling addAttribute() lets you put in an interface of type IAttribute. I have given you two examples below.
*
* ChokeValue's constructor ONLY takes a string because caluations to get choke value can be done without calling unity functions.
*
* UpHill's constructor takes a string and a HillCalculator. It's annoying, but this is necessary because it requires MonoBehaviour to do it's calculations.
* Whenever you're trying to make an attribute that requires extra infomation from the gameworld, you need to make it like UpHill. Basically you need another
* MonoBehaviour Object (Like hill Calculator), and you need to attach it to the terrain you'r analyzing. Again this is annoying but it's necessary because
* of how unity objects work. Take a look at upHill and you should see how it's working.
