 (This is a special kind of table called (in Eden terminology) a "superentity". This is like a superclass
 but for database tables. Records in multiple specialized tables have "parent" records in a shared
 superentity table, so other tables can refer to any of the specialized tables without needing a foreign

+Why do we want a separate table? Why not just add a category and location to the msg_message table?
+Eventually, we want to do "human intelligence task" processing, in which results are verified by
+sending the same task to multiple workers, and comparing the results. So we may have more than one
+set of results for each message. We want to include which worker did each task, so we can check
+the quality of their work and refer them to more training if needed.
