Concepts
concept	helios::ecs::ConstComponentTrait
	Concept for const-qualified component types.
concept	helios::ecs::ComponentTrait
	Concept to check if a type can be used as a component.
concept	helios::ecs::ComponentWithNameTrait
	Concept for components that provide a static name method.
concept	helios::ecs::TagComponentTrait
	Concept for tag components (empty).
concept	helios::ecs::TrivialComponentTrait
	Concept for trivially copyable components (POD-like).
concept	helios::ecs::TinyComponentTrait
	Concept for tiny components (single cache line portion), where sizeof(T) <= 16.
concept	helios::ecs::SmallComponentTrait
	Concept for small components that fit in cache line, where sizeof(T) <= 64.
concept	helios::ecs::MediumComponentTrait
	Concept for medium components (multiple cache line portions), where 64 < sizeof(T) <= 256.
concept	helios::ecs::LargeComponentTrait
	Concept for large components that don't fit in cache line, where sizeof(T) > 256.
