Pulling string data from XML

To get string data out of XML, we're going to create a singleton class that can be accessed anywhere to get at the strings and constants for each string's ID.

Building the Strings class

To start, create a new class in the ui folder named Strings. This class won't extend anything, and it should be in the ui package.

Here's what it should look like to start:

package ui;
class Strings
{
  public function new() {}
}

Next, add the following imports:

import haxe.xml.Fast;
import openfl.Assets;

The new class in use here is the Fast class, which is Haxe's XML handling class.

After this, add the code needed to use this class like a singleton:

public static var instance(get, null):Strings;
 private static function get_instance():Strings {
    if(instance == null) {
       instance = new Strings();
   }
    return instance;
}

This works exactly like the singleton setup in the SoundManager class does. As such, we'll also need to make our constructor private:

private function new()...
