Missing simulation time in events
We are trying to put more emphasis on different type of models, that need not be time progressing. Furthermore, from the ExchangeItemChangeEventArgs you can get to the exchange item and from there to the linkable component, which has the required information. 
Discussion turned into whether the ExchangeItemValueChanged event should be moved to the exchange item, such that you can register for a specific exchange item directly and do not need to register globally and filter out the exchange item that are not relevant. Would be preferable to have in case of distributed computation. But it is a bit more difficult to register in case you want to listen for all ExchangeItemValueChanged events. We move the event to the exchange item
