Ember Simple Auth Configurable Authentication Route Mixin

configurable-authentication-route-mixin.js

// For use with the Ember Simple Auth Addon. This is one way to default to
// using authentication required routes. For a preferred solution see:

  // change this value in this file. Only change needsAuthentication in the 
  // route.js file for the route that does not need authentication.
