Issue#28

User can now specify nested json schemas in request and response. The nested objects e.g. list or dict will be added as example to keep things simple. As parsing each nested object will make schema very complex with increased nesting levels. With this simple approach user can add any level of nesting to json and yaml generated will be simple.

Example

request_schema = {
    "id": 10, 
    "name": "level01", 
    "nested_dict": {
        "id":1, 
        "name":"level02",
        "values" : {
            "id": 3,
            "name": "level03"
        }
    }, 
    "nested_list": [
        {"a":1},
        {"b":2}
    ]
}

@generator.request_body(request_schema)
@blueprint.route('/objects/<int:object_id>', methods=['PUT'])
def update_object(object_id):
    return jsonify({'id': 1, 'name': 'test_object_name'}), 201
