# Challenge 1: Given a list of integers, create a module that maps that list
# into different processes. Deliver to those processes the element and a
# function to be performed with it. This function can be anything, for
# instance: "Returns square of the number". Finally each process shoud send
# a message to the spawning process with the result.

defmodule Spawner do
  @moduledoc """
  Maps a list into processes performing a given function. Each one sends a
  message to the spawning process, this one uses the IO module to print it out.
