-/*
-Serpentity is a simple entity framework inspired by Ash.
-
-Usage:
-
-    let Serpentity = require('serpentity');
-
-## Instantiating an engine
-
-    let engine = Serpentity();
-
-Add entities or systems, systems are added with a priority (the smaller
-the number, the earlier it will be called):
-
-    engine.addEntity(entityFactory());
-    engine.addSystem(new GameSystem(), priority);
-
-Update all systems:
-
-    engine.update(dt);
-
-Remove entities or systems:
-
-    engine.removeEntity(entityReference);
-    engine.removeSystem(systemReference);
-
-## Creating Entities
-
-Entities are the basic object of Serpentity, and they do nothing.
-
-    let entity = new Serpentity.Entity();
-
-All the behavior is added through components
-
-## Creating Components
-
-Components define data that we can add to an entity. This data will
-eventually be consumed by "Systems"
-
-    let PositionComponent = class PositionComponent extends Serpentity.Component {
-      constructor (config) {
-        this.x = 0;
-        this.y = 0;
-
-        super(config);
-      }
-    };
-
-You can add components to entities by using the add method:
-
-    entity.addComponent(new PositionComponent());
-
-
-Systems can refer to entities by requesting nodes.
-
-## Working with Nodes
-
-Nodes are sets of components that you define, so your system can require
-entities that always follow the API defined in the node.
-
-    let MovementNode = class MovementNode extends Serpentity.Node;
-    MovementNode.position = PositionComponent;
-    MovementNode.motion = MotionComponent;
-
-You can then request an array of all the nodes representing entities
-that comply with that API
-
-    engine.getNodes(MovementNode);
-
-## Creating Systems
-
-Systems are called on every update, and they use components through nodes.
-
-    let TestSystem = class TestSystem extends Serpentity.System {
-      added (engine){
-        this.nodeList = engine.getNodes(MovementNode);
-      },
-      removed (engine){
-        this.nodeList = undefined;
-      }
-      update (dt){
-        let node;
-        for (node of this.nodeList) {
-          console.log(`Current position is: ${node.position.x},${node.position.y}`);
-        }
-      }
-    };
-
-## That's it
-
-Just run `engine.update(dt)` in your game loop :D
