Structure for tests

[eduardo-rodrigues]

Hi, this PR starts adding some structure for tests as we have them in Scikit-HEP packages.

Starts addressing #12 and #4 to some extent.

With this I can see the tests running issuing python -m pytest tests/test.py -vv under the main directory. Of course there is no CI set up here, so that will have to come ...

Hi @ast0815, is this easy PR being forgotten …?

Could you make it so the output of the tests is printed to the logs? I.e. I'd like to be able to look at the histograms (even if it is without colour) that get produced. I'm not that familiar with pytest, but I think there is a command line flag that does this.

To be honest, @ast0815 I would prefer to do that or have it done in a different PR. For one, that's a different matter from this PR on structure. Also, I'm totally overloaded at the moment and do not exactly know how to do what you suggest, so no way I can do it "just now". But if you create an issue for your suggestion I will try and help next week.

If agreed, just approve, squash and merge :-).

Perfect, thanks!
