Copyright and licensing

[euronion]

I added new copyright and licensing information to all files and made
the repository (nearly) REUSE compliant.

Somehow some minor commits got mixed up in this PR (sorry, i don't want
make the effort of taking them out of this PR).

@coroa Please let me know if you agree with this.

Did you remove the package doc string intentionally? It is what is displayed, when you import the library. And then ask for help for it, ie

import atlite
?atlite

Instead I would like to extend it with a link to the documentation and perhaps one or two very simple examples.

Yes, multiple reasons:

• Previous one was so out-of-date it was more confusing than helping.
• The docstring was repeated in every section of the API ref. generated by automodule on readthedocs.org - not something beautiful to look at.
• I didn't have a nice substitute.

I'd drop the examples (Pareto principle + we are working on nice examples in parallel). So I argue no need to open up a new frontier there IMHO.
Let's stick to a simple description, suggestion in the updated PR.

Thanks for that tedious work! Looks good and i would merge soonish, so that we do not pick up anymore conflicts!

Happy to hear & you're welcome!
Agreed, let's hopefully merge soon, I have already some more local merge conflicts because of this.

I merged upstream into my local and resolved the merge conflicts.
Hopefully I didn't make a mistake out of lacking attention and sleep.

If you're ok with the result, then please push the button. :)
