'귀 밑에서 턱까지 잇따라 난 수염을 구레나룻이라고 한다.'

Setting rules with csv file. (you only need to use `set_rules_by_csv()` method.)

```bash

$ cat test.csv

인덱스,단어

1,네이버영화

2,언급된단어

```

```python

>>> from pykospacing import Spacing

>>> spacing = Spacing(rules=[''])

>>> spacing.set_rules_by_csv('./test.csv', '단어')

>>> spacing("김형호영화시장분석가는'1987'의네이버영화정보네티즌10점평에서언급된단어들을지난해12월27일부터올해1월10일까지통계프로그램R과KoNLP패키지로텍스트마이닝하여분석했다.")
