Create help pop-up class

Help is a class / pop up that is design to give information on the page you are on. The idea being that if you are on the Main Menu, and click on help, then you will go to the Help class that contains a hashMap. "Main Menu" will then be the key to find the value which is information on "Main menu". HashMap<String, String> helpRegister = new HashMap<>(); This can either be displayed by creating a new scene, or a popup.
