Releasing full standard, reflecting all suggested requests, including SDK and GUI.

Documentation:
IExchangeItem.ElementSet == null : spatially independent
IExchangeItem.ElementSet.ElementCount == 0 : spatially dependent but no values available yet.
IExchangeItem.TimeSet == null : Time independent.
IExchangeItem.TimeSet.Times == null : No meaning, not allowed.
IExchangeItem.TimeSet.Times.Count == 0 : Time dependent, but no values available yet.
Limited resources within OATC for testing and development, in order to get as well the standard as the SDK "correct".
