Handles singleton component lifecycle and injection. Makes it easy to locate and access singleton components.
Using this plugin can help decouple systems, follow a stateless/pure behavior system pattern, and make it easier to serialize system state.
Some example singletons: Configuration, Map, Keybindings, Console, Score, Player, Camera.
