Project/Exercise 14 : List remove duplicates (https://www.practicepython.org/)
                      Write a program (function!) that takes a list and returns a new list that contains all the elements
                      of the first list minus all the duplicates.

                      Extras:
                      Write two different functions to do this - one using a loop and constructing a list, and another using sets.
                      Go back and do Exercise 5 using sets, and write the solution for that in a different function.
