     * @description
     *
     * Object containing default options to pass when setting cookies.
     *
     * The object may have following properties:
     *
     * - **path** - `{string}` - The cookie will be available only for this path and its
     *   sub-paths. By default, this is the URL that appears in your `<base>` tag.
     * - **domain** - `{string}` - The cookie will be available only for this domain and
     *   its sub-domains. For security reasons the user agent will not accept the cookie
     *   if the current domain is not a sub-domain of this domain or equal to it.
     * - **expires** - `{string|Date}` - String of the form "Wdy, DD Mon YYYY HH:MM:SS GMT"
     *   or a Date object indicating the exact date/time this cookie will expire.
     * - **secure** - `{boolean}` - If `true`, then the cookie will only be available through a
     *   secured connection.
     * - **samesite** - `{string}` - prevents the browser from sending the cookie along with cross-site requests.
     *   Accepts the values `lax` and `strict`. See the [OWASP Wiki](https://www.owasp.org/index.php/SameSite)
     *   for more info. Note that as of May 2018, not all browsers support `SameSite`,
     *   so it cannot be used as a single measure against Cross-Site-Request-Forgery (CSRF) attacks.
     *
     * Note: By default, the address that appears in your `<base>` tag will be used as the path.
     * This is important so that cookies will be visible for all routes when html5mode is enabled.
     *
     * @example
     *
     * ```js
     * angular.module('cookiesProviderExample', ['ngCookies'])
     *   .config(['$cookiesProvider', function($cookiesProvider) {
     *     // Setting default options
     *     $cookiesProvider.defaults.domain = 'foo.com';
     *     $cookiesProvider.defaults.secure = true;
     *   }]);
     * ```
