     *
     * The constructor takes a single argument. The argument can be a string, in which case it
     * should be the API key. It can also be an array with various configuration settings.
     *
     * Configuration settings include the following options:
     *
     * - api_key (null|string): the Stripe API key, to be used in regular API requests.
     * - app_info (null|array): information to identify a plugin that integrates Stripe using this library.
     *                          Expects: array{name: string, version?: string, url?: string, partner_id?: string}
     * - client_id (null|string): the Stripe client ID, to be used in OAuth requests.
     * - stripe_account (null|string): a Stripe account ID. If set, all requests sent by the client
     *   will automatically use the {@code Stripe-Account} header with that account ID.
     * - stripe_context (null|string): a Stripe account or compartment ID. If set, all requests sent by the client
     *   will automatically use the {@code Stripe-Context} header with that ID.
     * - stripe_version (null|string): a Stripe API version. If set, all requests sent by the client
     *   will include the {@code Stripe-Version} header with that API version.
     *
     * The following configuration settings are also available, though setting these should rarely be necessary
     * (only useful if you want to send requests to a mock server like stripe-mock):
     *
     * - api_base (string): the base URL for regular API requests. Defaults to
     *   {@link DEFAULT_API_BASE}.
     * - connect_base (string): the base URL for OAuth requests. Defaults to
     *   {@link DEFAULT_CONNECT_BASE}.
     * - files_base (string): the base URL for file creation requests. Defaults to
     *   {@link DEFAULT_FILES_BASE}.
     * - meter_events_base (string): the base URL for high throughput requests. Defaults to
     *   {@link DEFAULT_METER_EVENTS_BASE}.
