/**
 * Wrapper type for relation type definitions in entities.
 * Used to circumvent ESM modules circular dependency issue caused by reflection metadata saving the type of the property.
 *
 * Usage example:
 * @Entity()
 * export default class User {
 *
 *     @OneToOne(() => Profile, profile => profile.user)
 *     profile: Relation<Profile>;
 *
 * }
