Also make use of blank lines more liberally.
Component System inspired by Artemis.

Typical "EntityComponentSystems" (ECS) involve a GameObject (think Entity)
that has multiple attributes or "Components" that are highly modular. To
define some terms...

- GameObject: Any object in the engine. For our example, Minecraft is our
  engine and Entity would be a GameObject.
- Components: Data holders, no logic.
- ComponentSystem: Processes all GameObjects that have certain Components
  on each game loop or manul processing.
- ComponentManager: Tracks all ComponentSystems as well as what Components
  a GameObject currently has. Handles passing off GameObjects to
  ComponentSystems if they meet the filter criteria. Also handles
  processing each ComponentSystem (if it can be processed)

Having a modular system brings many perks; one of the biggest being the
ability to "build your own" GameObject. Refer to the javadocs for
specifics.
