Entity handling types.
An entity exclusively owns zero or more component instances, all of different types, and can dynamically acquire or lose them over its lifetime.

or from the outside (or from an exclusive system) by directly using World methods:
| Operation | Command | Method |

| Spawn a new entity | Commands::spawn | World::spawn |
| Spawn an entity with components | Commands::spawn_bundle | — |
| Despawn an entity | EntityCommands::despawn | World::despawn |
| Insert a component to an entity | EntityCommands::insert | EntityMut::insert |
| Insert multiple components to an entity | EntityCommands::insert_bundle | EntityMut::insert_bundle |
| Remove a component from an entity | EntityCommands::remove | EntityMut::remove |
