Handle "nullable" array types #121
Description
If given "nullable":true in schema - array value still fails on null value.
Suggested patch to schemas.py:
class Model:
"""
A Model is a representation of a Schema as a request or response. Models
are generated from Schema objects by called :any:`Schema.model` with the
contents of a response.
"""
__slots__ = ["_raw_data", "_schema"]
def __init__(self, data, schema):
"""
Creates a new Model from data. This should never be called directly,
but instead should be called through :any:`Schema.model` to generate a
Model from a defined Schema.
:param data: The data to create this Model with
:type data: dict
"""
