Changelog

• 0.1.2: Removed stop_stats.txt in favor of making stop_time_stats.txt a statistical summary file instead of list-like. Similarly, made trip_stats.txt a statistical summary file instead of list-like. Finally, aligned statistical fields between trip_stats.txt, route_stats.txt, and group_stats.txt
• 0.1.1: Add new file stop_stats.txt for aggregation statistics at stop level. Update trip_stats.txt and stop_time_stats.txt to remove time windows, since these are containers for raw data rather than aggregations. Fix value types of aggregation fields from int->float. Clarify required vs optional for aggregation definition fields.
• 0.1.0: initial commit
