-/// When containers are finally ECS'd have this attach to the container entity.
-/// The <see cref="Solution.MaxVolume"/> field should then be extracted out into this component.
-/// Solution entities would just become an apporpriately composed entity hanging out in the container.
-/// Will probably require entities in components being given a relation to associate themselves with their container.
