Add __init__ for pydantic classes

[Nathan-Nesbitt]

Based on some comments.

As Pydantic doesn't display the variables that are defined in the class:

We can add the __init__ to each of the classes which would allow for VSCode to pick up on what parameters the class takes. This would reduce the time required to look at the docs for required parameters, but would require more code in each class.

So you can do either:

    def __init__(self, **data):
        """My modified docstring"""
        super().__init__(**data)

Or:

ExampleModel.__init__.__doc__ = 'My modified docstring'

I suspect the latter will not be picked up by VSCode though

I will try out the first one, but I will show you what I was hoping to achieve:

This is with nothing

This is with the first solution

This is what I was hoping to achieve

I think there may be a different way of solving the input types using pylance based on this PR but I haven't gotten it working yet.

Found a way, unfortunately based on that PR the proper solution to this will not be available until a new standard has been adapted in python. The solution involves making changes to pydantics source and works remarkably well. The following is using the changes defined in that link, along with pylance:

No need for the __init__.

The interesting part is that the pydantic repo actually already contains these changes but there hasn't been a release since may.

We can install from GIT instead of PYPI and it works:

pip install git+git://github.com/samuelcolvin/pydantic@master#egg=pydantic
