Create an Ember application instance that can be imported into any file. Useful for container lookups in files outside of the usual hierarchy.

application.js

// app/instance-initializers/application.js
import appInst from 'appName/utils/application'
export function initialize( appInstance ) {
  appInst.instance = appInstance
}

export default {
  name: 'application',
  initialize
};

messages.js

// app/validations/messages.js
//
// Sample usage. Here we are injecting the ember-i18n service into an Ember.Object
// to translate the validation messages used in ember-changeset-validations

import Ember from 'ember'
import application from 'appName/utils/application'

const Messages =  Ember.Object.extend({
  i18n: Ember.computed(function() {
    return application.instance.lookup('service:i18n')
