 ## Overview
 
 In EntityX data associated with an entity is called a `entityx::Component`. `Systems` encapsulate logic and can use as many component types as necessary. An `entityx::EventManager` allows systems to interact without being tightly coupled. Finally, a `Manager` object ties all of the systems together for convenience.
