// This class provides a simple implementation for IObjectSafety for
// for object that are either always safe or always unsafe for scripting
// and/or initializing with persistent data.
//
// The constructor takes an IUnknown interface on an outer object and delegates
// all IUnknown calls through that object.  Because of this, the object must
// be explicitly destroyed using C++ (rather than COM) mechanisms, either by
// using "delete" or by making the object an embedded member of some other class.
//
// The constructor also takes two booleans telling whether the object is safe
// for scripting and initializing from persistent data.
