      Creates a new TLcdSelectionChangedEvent with the given information.
      Parameters:
      aSelection - the ILcdSelection that is firing this TLcdSelectionChangedEvent.
      aSelectedObjects - the objects for which the selection state changed from not selected to selected.
      aDeselectedObjects - the objects for which the selection state changed from selected to not selected. Note: an object should only be in one of the vectors, not in both.

      Creates a new TLcdSelectionChangedEvent with the given information.
      Parameters:
      aSelection - the ILcdSelection that is firing this TLcdSelectionChangedEvent.
      aSelectionChanges - the Map containing the selection changes. The keys of this Map must be the objects whose selection states have changed. The value associated to a given key must be a Boolean instance that is true if the Object has been selected or false if it has been deselected. It is recommended to use an IdentityHashMap.
