This is preparatory work towards adding a Topic model. We plan to use the local variable name as 'topic' for the Topic model objects. Currently, we use *topic as the local variable name for topic names. We rename local variables of the form *topic to *topic_name so that we don't need to think about type collisions in individual code paths where we might want to talk about both Topic objects and strings for the topic name.
