// Usage:
//  $.cookie('mine', 'data', 5*60*1000)  -- write data to cookie named mine that lasts for five minutes
//  $.cookie('mine')                     -- read the cookie that was just set, function result will be 'data'
//  $.cookie('mine', '', -1)             -- delete the cookie

    // read cookie
    var cookies = document.cookie.split(';')

      var c = cookies[i].replace(/^\s+/, '')

  // write cookie
