// HepFileSwitch.cc - definition of class HepFileSwitch
//
// Intended to give the user access to the leftover objects when
// HepFileManager::switchFile is called. That function can deal with TH1
// objects, TDirectory objects and TTree objects. A pointer to any TObject
// that is not one of these three is inserted into a 
//
//		std::vector<TObject*> strays
//
// and passed on to a virtual member function of this class for disposition.
// The strategy is that this is implemented as a base class with a
// do-nothing, virtual member function.  The user should write a
// descendent class which overrides this member function with whatever code
// may be appropriate for his/her application. 
//
