Create a full test

We should have a repo which is the result of pod-template which specific arguments. Then a test that runs though the same options and then does a diff on output.

Similar to https://github.com/QueryKit/mogenerator-template/blob/master/Makefile#L7-8. We don't need any complex ruby, simple diff does the job.

This should give us more visibility on the [output and how it looks](https://github.com/QueryKit/mogenerator-template/tree/master/Example), and also allows us to know when we unintentionally break something.

Inspect how pod-template is invoked and determine the specific arguments that should produce the checked-in repository. Compare the linked mogenerator-template Makefile lines 7-8 for the simple diff approach, then verify that the generated output matches the fixture and that the test detects unintended changes.
