Does it work? I tried 

`$ pip install -e git+https://github.com/tpeng/python-crfsuite.git#egg=python-crfsuite`

and then got this error:

```
python -c 'import pycrfsuite'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/kmike/envs/scraping/src/python-crfsuite/pycrfsuite/__init__.py", line 6, in <module>
    from .pycrfsuite import PyTrainer, PyTagger, PyAttribute
ImportError: No module named pycrfsuite

```
