This will now work with 2.0.0

Hmm actually this will still not load the mixpanel js correctly. Maybe need to upstream some changes from https://github.com/sportly/ember-cli-mixpanel-service (which works for me under ember 2.0.1/ember-cli 1.13.8)

@parkan can you detail what you've done?

[parkan]

@zkwentz sorry, it's been a while. From what I remember I moved the container-dependent code to the instance initializer, because the initializer call signature has changed from initialize: function(container, application) to initialize: function(registry, application) (so the container is now only present in the instanceInitializer call)

This allows the addon to boot, but the external mixpanel dependency still wasn't loading for me after the fix.
