This table holds text labels that are to be rendered onto map images. The data may be transitory, in which case ServicePlanner will take responsibility for tidy-up, or long-lived, in which case the text will remain in the database until tidied by a system administrator. The text data is grouped according to the pair of columns (user_id, group_index). ServicePlanner will map grouped text in the same style, remove them as a group and display either all the text in a group or not at all.
