PropChanged() public method

When we get a PropChanged, it is really meant for our m_notifiee. However, it may have invalid arguments for ivMin etc, because the item(s) inserted or deleted in the real property may be in a different (or no) place in the filtered property. Rather than trying to figure out what really changed, we issue a PropChanged which is interpreted as changing the whole property.
public PropChanged ( int hvo, int tag, int ivMin, int cvIns, int cvDel ) : void
