//Cookie front end handler ( extending JS with cookie object - Prototype style)
//based on Jason McCreary creation - http://jason.pureconcepts.net/articles/javascript_cookie_object

/* Example Usage
Cookie that expires 90 days from visit, and sets a value:
    Cookie.init({name: 'yourdata', expires: 90});
    Cookie.setData('favorites', false);

Cookie that only lasts the session, with default data:
    Cookie.init({name: 'mydata'}, {foo: 'bar', x: 0});
    alert(Cookie.getData('foo'));
