[Compose] 13. Lift into a Pointed Functor with of

We examine the of function we've seen on a few types and discover it's the Pointed interface.

Instead of doing constructor way of Task:

const useTask= (x) =>
  new Task((rej,  res) => res(x))

We can just say:

Task.of("something"); //Task("something")
Either.of("something"); // Either("something");
Box.of(); // Box(100)
