// Summary: Application entry point (Connect IQ AppBase): lifecycle, first view, glance, locking on exit.
//
// Connect IQ lifecycle: initialize -> onStart -> getInitialView (or
// getGlanceView in glance mode) -> views run -> onStop.
//
// The vault is opened in getInitialView, not onStart: onStart also runs in
// glance mode, which has too little memory for it.
//
// Security: onStop locks the vault (keys and decrypted codes are wiped). It
// runs when the user leaves the app, and also when Garmin's system passcode
// shuts running apps down.
//
// getGlanceView is (:glance), so the compiler checks this class against the
// glance scope too. The other methods never run in glance mode and use
// non-glance code, so they opt out with (:typecheck(disableGlanceCheck)).
