LiveSlider class abstract
A Slider with its value
controlled by a MutableCell.
The value
is controlled by a MutableCell which is passed on construction.
When the value of the cell changes, the slider position is updated to reflect
the value of the cell. Similarly when the slider is moved by the user, the
value of the cell is updated to reflect the slider position.
The cell provided for enabled
controls whether the widget is enabled for user
interaction, when the value of the cell is true, or disabled, when the value
of the cell is false.
