This adds a very simple frontend UI and class functionality to the app.
It's not pretty at all yet (I'm still working on that, I wasn't liking any styles I tried yet) but it's a solid start to work off of.
In this case, the value is the same as this.value. All other variables by that name have since gone out of scope. It shouldn't matter for anything except style. The difference is in the setters, where I have a class level and method level of the same name, and it will default to the method level variable without a this.
