Gesture Recogniser for wavingPicker

- Added a gesture recogniser to detect a tap on the wavingPicker to allow for the selection of the UISwitch.
- Added delegate for UIGestureRecognizer so we can allow multiple gestures, which would normally conflict.
- Added notes to "tappedPickerView:" which explains the code and how to handle it

NB: Haven’t been able to test in the app, but did a quick test using the same code in a dummy project and it worked as intended.
