Can anyone give a description of each of the 5 setup methods?

(void) setupCoreDataStack;
(void) setupAutoMigratingDefaultCoreDataStack;
(void) setupCoreDataStackWithInMemoryStore;
(void) setupCoreDataStackWithStoreNamed:(NSString *)storeName;
(void) setupCoreDataStackWithAutoMigratingSqliteStoreNamed:(NSString *)storeName;

What do they each do and what is the use case for each?
