/* 

Errors checked:

make some BackupDirectoryStore objects, CheckAndFix(), then verify
	- multiple objects with same ID
	- wrong order of old flags
	- all old flags

delete store info
add spurious file
delete directory (should appear again)
change container ID of directory
delete a file
double reference to a file inside a single dir
modify the object ID of a directory
delete directory, which has no members (will be removed)
extra reference to a file in another dir (higher ID to allow consistency -- use something in subti)
delete dir + dir2 in dir/dir2/file where nothing in dir2 except file, file should end up in lost+found
similarly with a dir, but that should get a dirxxx name
corrupt dir
corrupt file
delete root, copy a file to it instead (equivalent to deleting it too)
