Added method to calculate the daily logs.

extended TimeLogList object:
 > to group logs into days with the "DailyLogs" object
 > to calculate the WeeklyTotal hours automatically based on the TimeLogs.DailyLogs object for each day.

Created DailyLogs object:
 > holds the number of entries for a day.
 > holds the time "in"/"at work" for that day (dailytotal).
