python package to read and write the
[Newick format](https://en.wikipedia.org/wiki/Newick_format).


## Reading Newick

- From a string:
```python
>>> from newick import loads
>>> trees = loads('(A,B,(C,D)E)F;')
>>> trees[0].name
u'F'
>>> [n.name for n in trees[0].descendants]
[u'A', u'B', u'E']
```

- From a `file`-like object:
```python
>>> import io
>>> from newick import load
>>> with io.open('fname', encoding='utf8') as fp:
... trees = load(fp)
```

- From a file name:
```python
>>> from newick import read
>>> trees = read('fname')
```

## Writing Newick

In parallel to the read operations there are three functions to serialize a single `Node` object or a `list` of `Node`
objects to Newick format:
- `dumps(trees) -> str`
- `dump(trees, fp)`
- `write(trees, 'fname')`

A tree may be assembled using the factory methods of the `Node` class:
- `Node.__init__`
- `Node.create`
- `Node.add_descendant`
