+// The following helper classes are placeholders for a generic "singleton"
+//  class.  The classes below support usage of singletons, including use in
+//  program startup/shutdown code, AS LONG AS there is only one thread
+//  running before main() begins, and only one thread running after main()
+//  exits.
+//
+// This class is also limited in that it can only provide singleton usage for
+//  classes with default constructors.
+//
+
+// The design of this class is somewhat twisted, but can be followed by the
+//  calling inheritance.  Let us assume that there is some user code that
+//  calls "singleton_default<T>::instance()".  The following (convoluted)
+//  sequence ensures that the same function will be called before main():
+//    instance() contains a call to create_object.do_nothing()
+//    Thus, object_creator is implicitly instantiated, and create_object
+//      must exist.
+//    Since create_object is a static member, its constructor must be
+//      called before main().
+//    The constructor contains a call to instance(), thus ensuring that
+//      instance() will be called before main().
+//    The first time instance() is called (i.e., before main()) is the
+//      latest point in program execution where the object of type T
+//      can be created.
+//    Thus, any call to instance() will auto-magically result in a call to
+//      instance() before main(), unless already present.
+//  Furthermore, since the instance() function contains the object, instead
+//  of the singleton_default class containing a static instance of the
+//  object, that object is guaranteed to be constructed (at the latest) in
+//  the first call to instance().  This permits calls to instance() from
+//  static code, even if that code is called before the file-scope objects
+//  in this file have been initialized.
