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.

empty entity: Entity with zero components. pending entity: Entity reserved, but not flushed yet (see Entities::flush docs for reference). reserved entity: same as pending entity. invalid entity: pending entity flushed with invalid (see Entities::flush_as_invalid docs for reference).

See Entity to learn more.
