Cell

trait Cell [T] extends Dependent

A wiring Cell. A Cell can be a ValueCell which holds a value which can be set (and thus update the dependencies), a FuncCell (a cell that is a function that depends on other cells), or a DynamicCell which has a value that updates each time the cell is accessed.
