\class HbTumbleView
\this is a tumbler widget which lets the user select alphanumeric values from a predefined list of

Tumbler. The Tumbler could also be used to change other values such as number code sequence,
landmark coordinates, country selection, and currency.
Only strings can be accepted as HbTumbleView's items.
