  Starts a stand-alone instance of Pixie.  Probably only good for development and testing.

  ## Command line options

  This task accepts the same command-line arguments as `app.start`. For additional
  information, refer to the documentation for `Mix.Tasks.App.Start`.

  For example, to run `pixie.server` without checking dependencies:

    mix pixie.server --no-deps-check
