    A factory to create new :py:class:`~boto3.resources.base.ServiceResource`
    classes from a :py:class:`~boto3.resources.model.ResourceModel`. There are
    two types of lookups that can be done: one on the service itself (e.g. an
    SQS resource) and another on models contained within the service (e.g. an
    SQS Queue resource).

a{
        Loads a resource from a model, creating a new
        :py:class:`~boto3.resources.base.ServiceResource` subclass
        with the correct properties and methods, named based on the service
        and resource name, e.g. EC2.Instance.

        :type resource_name: string
        :param resource_name: Name of the resource to look up. For services,
                              this should match the ``service_name``.

        :type single_resource_json_definition: dict
        :param single_resource_json_definition:
            The loaded json of a single service resource or resource
            definition.

        :type service_context: :py:class:`~boto3.utils.ServiceContext`
        :param service_context: Context about the AWS service

        :rtype: Subclass of :py:class:`~boto3.resources.base.ServiceResource`
        :return: The service or resource class.

        the resource cannot be used. Identifiers become arguments for

        Actions on the resource become methods, with the ``load`` method
        being a special case which sets internal data for attributes, and

        Load resource attributes based on the resource shape. The shape
        name is referenced in the resource JSON, but the shape itself
        is defined in the Botocore service JSON, hence the need for
        access to the ``service_model``.

        Load resource collections from the model. Each collection becomes
        a :py:class:`~boto3.resources.collection.CollectionManager` instance
        on the resource instance, which allows you to iterate and filter
        through the collection's items.

        Load related resources, which are defined via a ``has``
        relationship but conceptually come in two forms:

        1. A reference, which is a related resource instance and can be
           ``None``, such as an EC2 instance's ``vpc``.
        2. A subresource, which is a resource constructor that will always
           return a resource instance which shares identifiers/data with
           this resource, such as ``s3.Bucket('name').Object('key')``.
