	Send event-count data to client in EventResponse instance
	Fix certain usages of gregorian calendar instead of julian
	Move HistDate, SCALES, etc, into cal.py
Frontend:
	Make App update a unitCountMaps object using event-count data from server
	Make TimeLine show visual indication of unit counts
	Add showEventCounts option to store
