/**
 `RLMProperty` instances represent properties managed by a Realm in the context
 of an object schema. Such properties may be persisted to a Realm file or
 computed from other data from the Realm.

 When using Realm, `RLMProperty` instances allow performing migrations and
 introspecting the database's schema.

 These property instances map to columns in the core database.
