'''
Exercise 14: List Remove Duplicates
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.
