How to use?

I'm not sure how to use this in my addons. For example, I have [ember-sinon-qunit](https://github.com/elwayman02/ember-sinon-qunit/blob/master/package.json), which depends on [ember-sinon](https://github.com/csantero/ember-sinon/blob/master/index.js), which has imports that need to execute on the app. However, I can't seem to figure out where/how to include this addon to make sure that all apps consuming ember-sinon-qunit will have ember-sinon's `index.js` execute properly.
