Title: Issue #13

Attempt to fix most obvious idioms related to issue #13 like

```python
if sys.version < '3':
from urllib import urlopen
from urlparse import urlparse
import ConfigParser
do_input = raw_input
else:
from urllib.request import urlopen
from urllib.parse import urlparse
import configparser as ConfigParser
do_input = input
```

Includes simplistic search for lowest common ancestor of nodes that could certainly be optimized.
