CellConstrainedBox class
ConstrainedBox widget with its properties controlled by ValueCells.
The constructor takes the same arguments as the unnamed constructor of ConstrainedBox, but as ValueCell's. This binds each property value to the ValueCell given in the constructor. If the cell value is changed, the value of the corresponding property to which it is bound is automatically updated to reflect the value of the cell.
