/* Rename Files Using Bookmarks */
// This is a script that can rename files based on bookmarks. 
// If document has 3 bookmarks the output filename is:
// First bookmark From Second Bookmark – Third Bookmark
// If there are more than 3 bookmarks, then output filename is:
// First bookmark From Second Bookmark To Third Bookmark – Forth Bookmark
