/**
* drop all events that are blocked by an exception
*
* some words on how it works:
*
* Basically the idea here is to check every event if it overlaps an exception.
*
* To make this algorithm a bit more efficant, these prerequisits are met:
* - the events are ordered by their start-date (no duplicate start dates),
* - the exceptions by their start-date (no duplicate start dates)
*
* So if we find, that the end-date of an exception is before the current start-date
* it is before the start-date of ALL remaining events and we'll just drop it.
*
