Dataset and modelling infrastructure for modelling "event streams": sequences of continuous time, multivariate events with complex internal dependencies.
Force foreign-key constraints among dfs so that all the events in events_df have matched subject_ids with subject_df, and all the measurements in dynamic_measurements_df have matched event_ids with events_df.
