EncryptedData.Decrypter	Decrypts some data.
EncryptedData.Encrypter	Encrypts some data.
Entity<ID extends EntityId>	An object that is not defined by its attributes, but rather by a thread of continuity and its identity.
EntityId	Identifies an entity within all entities of the same type.
EntityIdFactory	Factory to create entity identifier.
EntityType	Identifies a type of entity within all entity types of the context.
Event	Something that happened in the system.
