/**

* Class to store all calendar data (storage object)

|
|
* Tables used by socal:
|
|
* - egw_cal: general calendar data: cal_id, title, describtion, locations, ...
|
|
* - egw_cal_dates: start- and enddates (multiple entry per cal_id for recuring events!)
|
|
* - egw_cal_users: participant info including status (multiple entries per cal_id AND startdate for recuring events)
|
|
* - egw_cal_repeats: recur-data: type, optional enddate, etc.
|
|
* - egw_cal_extra: custom fields (multiple entries per cal_id possible)
|
|
*
|
|
* The new UI, BO and SO classes have a strikt definition, in which time-zone they operate:
|
|
* UI only operates in user-time, so there have to be no conversation at all !!!
|
|
* BO's functions take and return user-time only (!), they convert internaly everything to servertime, because
|
|
* SO operates only on server-time
