A base class for creating callable objects.
The way this works is that you subclass CallableObject and define a
constructor that calls super(someClosure) where someClosure is a unique
function object, which will then pick up any properties or methods defined by
the subclass.
(Note: It needs to be unique because the super() call only sets its
prototype, and returns the function you passed as this. So if you call it
with the same function more than once, you're just reinitializing the same
object instead of creating a new one.)
