def MakeNewConfig(self):
    """Creates a new configuration option based on this one.

    Note that it is not normally possible to just instantiate the
    config object because it will have an empty set of type
    descriptors (i.e. no config options will be defined). Config
    options are normally defined at import time, and then they get
    added to the _CONFIG global in this module.

    To obtain a new configuration object, inheriting the regular
    config options, this method must be called from the global _CONFIG
    object, to make a copy.

    Returns:
      A new empty config object. which has the same parameter definitions as
      this one.
