  This is an exs file just to mess around with some of the functionality of Exray.
  I run this with `clear && mix run ./lib/_examples/testbed.exs` from the root of the Exray project,
  which will clear the console of the last run (and it's errors) so we can catch new ones that pop up
  as we test the functionality of the bindings.

  So far, so good. :)
