cleans up for you !

example:

```go

func ProcessQuery()  (err error) {

	cleaner := NewCleaner(&err)

	defer cleaner.Clean()

	...

	// (some logic that needs to be executed only if ProcessQuery returns an error)

	cleaner.OnError(func(e err) {

		if e == ErrTxFailed {

			transaction.Rollback()

		} else {

			log.Errorf("failed request ID: %s", reqID)

		}

	})

	... 

	// (some logic that needs to be executed only if ProcessQuery returns no error)

	cleaner.OnNil(func() { log.Infof("request ID: %s succeded", reqID)

	...

	// (some logic that needs to be executed always no matter what)

	cleaner.Always(func() { wipebytes(thisByteSliceShouldBeZeroedAlways) })

	...

	return

}

```
