  Args:
    factory: a MessageFactory instance.
    full_name: str, the fully qualified name of the proto type.
  Returns:
    A class, for the type identified by full_name.
  Raises:
    KeyError, if the proto is not found in the factory's descriptor pool.

  Note: this doesn't validate field names!

  Args:
    fields: dict of {name: field_type} mappings for each field in the proto. If
        this is an OrderedDict the order will be maintained, otherwise the
        fields will be sorted by name.
    full_name: optional str, the fully-qualified name of the proto type.
    pool: optional DescriptorPool instance.
  Returns:
    a class, the new protobuf class with a FileDescriptor.
