Title: Made compatible with Python 3.

Added a default value to the sorted() call in process.py:38. Necessary because a glyph with no 'pen down' ends up with a start of None, and comparing None to a tuple during the sorted now causes a problem in python3.
Tested with python3.4 and 2.7, resulting in the same output file with both.
