Mimesis: Required docs [Sphinx]

[lk-geimfari]

Very required the documentation, because at this moment we have only small guidebook.

If it's alright with you, I'll give it a shot.

@Battleroid Thank you! Let me know about your final decision, please.

I would like to do these work. Let me know that if there is any need of updating the docStrings or not. One more question about the example, do you want examples included in the docs or not? :rocket:

[lk-geimfari]

@arpit1997 I think that docstrings is actual and recently updated. Yes, it would be good to include examples in the documentation. Everything should be in the 'docs' folder (root of repository). Thanks!

[Battleroid]

I'm going through and trying to put together the Sphinx documentation now. Some of the docstrings have very minor formatting issues so I'll fix those as well if that's ok.

@Battleroid Sorry for issues in docstrings. Thank you for your contribution!
