Add a nested bookmark under parent, or a new top level bookmark if parent 0. Returns a bookmark descriptor which may be used as parent for subsequent nested bookmarks. If open 1, child bookmarks will be folded out, and invisible if open 0.

Note that only the first call to strtok uses the string argument. Every subsequent call to strtok only needs the token to use, as it keeps track of where it is in the current string. To start over, or to tokenize a new string you simply call strtok with the string argument again to initialize it. Note that you may put multiple tokens in the token parameter. The string will be tokenized when any one of the characters in the argument are found.
