  A MCConfigurationExtended is a configuration with author initials, timestamp, comment, and a list of prior versions. Its external storage format is organized for compatibility with MCConfiguration, such that an image wtih support for only MCConfiguration can use configurations saved from a MCConfigurationExtended. The intended use is to enable documentation of configuration maps, and to allow modifications to a configuration map without loss of version history.!
