Could you upgrade your lib to python 3.x to be compatible with LibreOffice 4.x

This software is very useful to me. Could you upgrade to python3?

Give a try to my fork.

Installing under Raspbian/python3.4 I get this error/warning:

sudo python3 -m pip install oosheet

in python 2.7 there is no such message, yet the code appears the same so clearly the interpretation is slightly different
