// BLOGTOC
// ---------------------------------------------------
// BlogToc creates a clickable Table Of Contents for
// Blogger Blogs.
// It uses the JSON post feed, and create a ToC of it.
// The ToC can be sorted by title or by date, both
// ascending and descending, and can be filtered by
// label.
