	Now the constructor of AbstractDiskWriter takes filename as an
	argument and filename argument is removed from openFile(),
	initAndOpenFile(), openExistingFile() interface.  storeDir
	member and its accessor functions are removed from DiskAdaptor
	because it is not used anymore.  size() member function of
	DefaultDiskWriter, DirectDiskAdaptor and MultiDiskAdaptor now
	can be called without opening file.
