update for python3

[johnnybubonic]

even with the "conversion" and "exception" modules installed via pip:

...
from util import *
ModuleNotFoundError: No module named 'util'

I forked this and resolved the issue. The modules are already a part of the repo. I changed the imports in the source files to use relative paths. Works fine in py36. Not sure how well the project actually works.
