SINGLETON PATTERN - Coggle Diagram

- - - - How we create the first singleton?
        
        We use a static method which means that has access to the private constructor
        
        Singleton.GetInstance()
      - Singleton Instance
        
        (private) static Singleton instance
- - - - return new Singleton
        
        Since we are in the singleton class it doesn't matter that the constructor is private, we have access to the constructor
      - Method Logic
        
        Check if the static variable is null
        
        We instantiate the singleton and we store it in the variable
        
        If we have the singleton we return the variable
