Total refactor

[konradhalas]

This is a total refactor of dacite library.

I split everything into smaller modules, now real unit testing is finally possible. I also changed the way of building data class, current solution is much more generic, e.g. it supports fields like x: List[List[List[Union[int, X]]]]

@jasisz @bpeake-illuscio @rominf - It would be great if anyone of you could find the time to do a short code review.

@konradhalas, I'm not sure that I'll be able to do it faster than a week (have a tight schedule this week), but I'm definitely interested in this.

As for now, I don't like the commit messages, they are not descriptive. I think probably that you want to merge them into one if you cannot describe what you did clearly.

Also, consider splitting import into groups: typing and dataclasses should go into the first group, as they come with the standard library.

@rominf thank you, I want to merge it in a few days (probably during weekend) so it will be awesome if you could find some time.

I will squash everything into single commit.

Which file is wrong? I think that they are grouped as you said. I'm using PyCharm and it is done automatically.

In test files you have the following (or something like that):

import pytest
from dataclasses import dataclass, field
from typing import Any

Please change it to:

from dataclasses import dataclass, field
from typing import Any

import pytest

Ha, interesting, this is because I was using Python 3.6 locally and I had dataclass installed as a regular package from PyPI instead of standard lib module. Fixed.
