HoldDownButton class

The HoldDownButton is a StatefulWidget that can be held down to repeatedly trigger an action.

Uses a GestureDetector to detect a long press and a long press release to trigger or stop the repeated action.

If the child does not have an onTap method defined, the onHoldDown method will be called, else priority is given to the child's onTap method.
