users and groups:
* No: Every user can invite other users and groups (default and old
behavior)
* Groups: other users can allways be invited, only groups require an invite_grant
* Users + groups: inviting both allways requires an invite grant
One need to keep in mind, that setting an invitation ACL via a group,
gives each groupmember the right to invite the group / create a group
event. So the last option propable only works, if users manage
invitations grants on their own, or admin only sets it in small working
groups, where every member is allowed to invite the whole group.
--> calendar backend code removes participants a user is not allowed
to invite
- new "only groupevents" filter, showing only real groupenvents not
events of groupmembers (added tooltips to explain filters)

/**

* Class to access AND manipulate all calendar data (business object)
|

*
|
|
* 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
|
|
*
|
|
* As this BO class deals with dates/times of several types and timezone, each variable should have a postfix
|
|
* appended, telling with type it is: _s = seconds, _su = secs in user-time, _ss = secs in server-time, _h = hours
|
|
*
|
|
* All new BO code (should be true for eGW in general) NEVER use any $_REQUEST ($_POST or $_GET) vars itself.
|
|
* Nor does it store the state of any UI-elements (eg. cat-id selectbox). All this is the task of the UI class(es) !!!
|
|
*
|
|
* All permanent debug messages of the calendar-code should done via the debug-message method of the bocal class !!!
