* @param {String} [name] The name of the cookie.
* @param {String} [value] The value of the cookie.
* @param {{}} [options] An object literal containing key/value pairs to provide optional cookie attributes. Values can be:
* @option {Integer|Date} expires Either an integer specifying the expiration date from now on in days or a Date object. If a negative value is specified (e.g. a date in the past), the cookie will be deleted. If set to null or omitted, the cookie will be a session cookie and will not be retained when the the browser exits.
* @option {String} domain The domain name
* @option {String} path The value of the path atribute of the cookie (default: path of page that created the cookie).
* @option {Boolean} secure If true, the secure attribute of the cookie will be set and the cookie transmission will require a secure protocol (like HTTPS).

*
* $.cookie('the_cookie', 'the_value');
*
* Create a cookie with all available options.
*
* $.cookie('the_cookie', 'the_value', {
* expires: 7,
* path: '/',
* domain: 'jquery.com',
* secure: true
* });
*
* Create a session cookie.
*
* $.cookie('the_cookie', 'the_value');
*
* Delete a cookie by passing null as value. Keep in mind that you have to use the same path and domain
