Dep allows creation of a dependent Var on another Var allowing conversion between the two. This can be useful for
different representations of the same value. For example, in a graphical environment left, center, and right
are all different representations of the value (horizontal position). Maintaining three distinct values while
keeping them in-sync is painful. With Dep you can simply define one Var and two Dep values like:
val left: Var[Double] = Var(0.0)
val width: Var[Double] = Var(0.0)
val center: Dep[Double, Double] = Dep(left)(_ + (width / 2.0), _ - (width / 2.0))
val right: Dep[Double, Double] = Dep(left)(_ + width, _ - width)
Now, modification to left, center, or right will maintain the appropriate value for each without any additional
boilerplate.
