// finds the events in NotifyEvent
// check subscription to determine if the age related ones are deliverable now
// check subscriptions for each delivery type, i.e. there might be both smtp and inapp separately for the same event so it needs to know that and deliver accordingly
// remove the notify event after it's processed
//Older notes:
//### PLAN if it's an smtp delivery that fails and it's to someone who can be delivered in app then it should send an inapp notification of
//delivery failure and still delete the smtp delivery
//If it's not possible to notify the person via in app of the failed smtp then perhaps it notifies OPS personnel and biz admin personnel
//NEW NOTIFICATION SUBSCRIPTION EVENT TYPE:
//OPERATIONS_PROBLEMS - backup, notifications, out of memory, what have you, anyone can subscribe to it regardless of rights
//this is just to let people know there is a problem
//todo: create message here if not already set?
//todo: generate and attach report here?
//All items have an event date, for non time delayed events it's just the moment it was created
//which will predate this moment now if it's pre-existing

//when to deliver formula: NotifyEvent "EventDate"+NotifySubscription.AgeValue timespan - NotifySubscription AdvanceNotice timespan > utcNow
