Hi!

I used the spaCy package's list of swedish stop words as my source, and i believe this list is widely used for Swedish language processing.

Yes, I know other projects use a lot of stopwords. I always tried to use only the general ones without any meaning at all. I translated some as "eighteen" or "goodbye" which I would omit. But because I have no knowledge of Swedish language we can merge. Maybe someone improves it if needed. Can I ask you for the test too to make sure the language works with all component?

I see, i've removed some stop words now that i belive were not as suitable. I have also added a test for the Swedish stemmer aswell.

[RobertMartinis]

Can we merge, or is it something more that needs to be addressed?

Thank you, it is fine like this :)
