[course] Introduction to Functional Programming in OCaml

I'm taking the Ocaml course and abandoned the one of F# from Edx/Microsoft that started a couple weeks ago. The Ocaml course is of much better quality in my opinion.

The MOOC is starting today. Here's the course outline if you are interested:

- week 0 Introduction and overview

- week 1 Basic types, definitions and functions

- week 2 Basic data structures

- week 3 More advanced data structures

- week 4 Higher order functions

- week 5 Exceptions, input/output and imperative constructs

- week 6 Modules and data abstraction
