> Cayenne uses {{TreeMap}} internally to keep all model-related entities sorted (Entities, Attributes, Relationships, etc.)
> But eventually ordering is needed only for tools (e.g. Modeler), while in runtime it only creates unnecessary performance overhead.
> So we can use {{HashMap}} for runtime and sort data explicitly where it is really needed (project saving, UI, etc.)
