Presenting one task directly after another

[maryHoekstra]

Must find way to present the memory test directly after the pre-test survey (tried presenting in completion block, calling separate function, etc).

[maryHoekstra]

this works:
taskViewController.dismiss(animated: true, completion: { let svc = self.storyboard!.instantiateViewController(withIdentifier: "ViewController") as! ViewController self.present(svc, animated: true, completion: nil) })

However, there is a slight delay before the home screen is shown.
