  // STEP 2
  // ------
  //
  // Define some functions that call the api.  The goal is to provide
  // a thin wrapper of the api layer providing nicer feeling functions
  // rather than "get", "post" and friends.
  //
  // I generally don't like wrapping the output at this level because
  // sometimes specific actions need to be take on `403` or `401`, etc.
  //
  // Since we can't hide from that, we embrace it by getting out of the
  // way at this level.

  //
  // Return back a collection of functions that we would consider our
  // interface.  Most of the time it'll be just the list of all the
  // methods in step 2.
  //
  // Notice we're not returning back the `api` created in step 1?  That's
  // because it is scoped privately.  This is one way to create truly
  // private scoped goodies in JavaScript.

// let's return back our create method as the default.
