Sort calculation results of a historical discharge calculation based on their start date.
Therefore, there are two new inner classes TimerangeItem and HistoricalTimerangeItem that wrap
a W, Q, Timerange (and delta Q). WQTimerange and HistoricalWQTimerange now implement a sort()
that return the results (TimerangeItem or HistoricalWQTimerangeItem) sorted by their start date.
