Samsung TV cookie module

gistfile1.js

// Use this as a black-box module to replace joshlib!utils/cookie when developing with
// Samsung TV.
//
// It returns a function to be called with the following parameters:
// name - The key to store.
// data - The value associated with this key.
//
// NOTE: In order to use, you need to expose <script src='$MANAGER_WIDGET/Common/af/2.0.0/loader.js' type='text/javascript'></script>
// in your index file.
//
// This module will use Samsung's sf.core.localData function.
