Implementation of the Singleton Design Pattern to Unity MonoBehaviours. This is useful when you need a single instance of a class and wants to tweak its properties in the editor.

• creates the Singleton instance automatically
• Singleton is ready no matter where or when you need it in your code
• grants the Singleton uniqueness (just one active instance at time)
• if there is already an instance in the Scene, uses it
• optinally makes the instance persistent through scenes

This implementation is a work in progress and it's widely open to suggestions.
