Support round-tripping Newick with two annotations per node, one before and one after the length separator.
1.8.1
Bugfix: Make `unquoted_name` property work for nodes without names, too.
1.8.0
- Added `rename` method - since that seems to be most common kind of node visitor. - Added `strip_comments` method to remove comments from a `Node`. While it is already possible to remove comments upon parsing, this method makes this possible for parsed trees.
1.7.1
Bugfix: Quote node names containing whitespace, if `auto_quote` is set.
1.7.0
Big performance improvement of parser by switching to accumulated tokens.
1.6.0
Support reading key-value data from node comments.
