implement (<**>) using (=<<) and (<$>) #47

This version better reflects the documentation on L78:
-- | Witness that all things with (=<<) and (<$>) also have (<*>).

I was stumped by this exercise while going through https://github.com/system-f/fp-course
and came here looking for a solution. Eventually I figured out this formulation, which I think
is more fitting. It's actually not immediately obvious to me (a beginner) that (>>=) is
defined here.

Yeah sorry you got stuck. Both are equivalent. You can jump on chat and get help if you get stuck again. Cheers!

Are you sure you want to change the base?
