 A `Single` on the other hand is a special kind of family that holds exactly **one** entity with exactly **one** component for the entire lifetime of the Nexus. This may come in handy if you have components that have a [Singleton](https://en.wikipedia.org/wiki/Singleton_(mathematics)) character. Single components must conform to the `SingleComponent` protocol and will not be available through regular family iteration.
