MetaObject

Metadata corresponding to an Entity that represents an object.

An Entity represents an object when Entity#isObject is true

A MetaObject corresponds to an Entity by having the same MetaObject#id as the Entity#id.

A MetaObject is created within MetaScene#createMetaModel and belongs to a MetaModel.

Each MetaObject is registered by MetaObject#id in MetaScene#metaObjects.

A MetaModel represents its object structure with a tree of MetaObjects, with MetaModel#rootMetaObject referencing the root MetaObject.
