-/**
- * Bookmark processing in a simple way. It has some limitations, mainly the only
- * action types supported are GoTo, GoToR, URI and Launch.
- * <p>
- * The list structure is composed by a number of HashMap, keyed by strings, one HashMap
- * for each bookmark.
- * The element values are all strings with the exception of the key "Kids" that has
- * another list for the child bookmarks.
- * <p>
- * All the bookmarks have a "Title" with the
- * bookmark title and optionally a "Style" that can be "bold", "italic" or a
- * combination of both. They can also have a "Color" key with a value of three
- * floats separated by spaces. The key "Open" can have the values "true" or "false" and
- * signals the open status of the children. It's "true" by default.
- * <p>
- * The actions and the parameters can be:
- * <ul>
- * <li>"Action" = "GoTo" - "Page" | "Named"
- * <ul>
- * <li>"Page" = "3 XYZ 70 400 null" - page number followed by a destination (/XYZ is also accepted)
- * <li>"Named" = "named_destination"
- * </ul>
- * <li>"Action" = "GoToR" - "Page" | "Named" | "NamedN", "File", ["NewWindow"]
- * <ul>
- * <li>"Page" = "3 XYZ 70 400 null" - page number followed by a destination (/XYZ is also accepted)
- * <li>"Named" = "named_destination_as_a_string"
- * <li>"NamedN" = "named_destination_as_a_name"
- * <li>"File" - "the_file_to_open"
- * <li>"NewWindow" - "true" or "false"
- * </ul>
- * <li>"Action" = "URI" - "URI"
- * <ul>
- * <li>"URI" = "http://sf.net" - URI to jump to
