final case class DynamicCell[T](f: () => T) extends Cell[T] with Product with Serializable
A cell that changes value on each access. This kind of cell could be used to access an external resource. Warning the function may be accessed many times during a single wiring recalculation, so it's best to use this as a front to a value that's memoized for some duration.

Add a Dependent to this cell.
Add a Dependent to this cell. The Dependent will be notified when the Cell's value changes. Dependents are kept around as WeakReferences so they do not have to be explicitly removed from the List
