This is the code of the Introduction to Mix elixir tutorial.
To run the tests go in the kv_umbrella folder and run iex --sname node2 -S mix,
then, from the same folder but in a different terminal, run elixir --sname node1 -S mix test.
The node names are hardcoded, you might want to change them before running the test, or you can change your hostname to align with mine, as you prefer.
