Functions
template<typename AccessSpec>
auto	helios::ecs::details::FetchComponent (const Archetype &archetype, Entity entity, ComponentManager &components) -> ComponentAccessType_t< AccessSpec >
	Fetches a single component for the current entity from the archetype, returning the appropriate access type.
