What's that _create_or_edit_object method doing?

• It's a hook
• Uses the data assembled from all the Mappings to create a new target object:

sub _create_or_edit_object {
   # Useful for subclasses to override for post-mapping-processing
   # (in this version we don't use $source_object, but subclasses can).

   my ($self, $source_object, $newobj_data) = @_;

   # ...

}

• $newobj_data is a hashref of keys and values with which to create the new target object.
