Broken on python 3.5 #4

Closed kapsh closed 7 years ago

kapsh commented 7 years ago

xeger is completely unusable with python 3.5. 

Traceback (most recent call last):
  File "/home/kapsh/tmp/xeger/xeger/tests/test_xeger.py", line 119, in test_zero_or_more_non_greedy
    self.match(r'a*?')

KeyError: MIN_REPEAT

This is because re.sre_parse.parse(pattern) returns tuple of _NamedIntConstant instead of strings. Fix with type conevrsion and normalization: #5 Checked on 3.5 and 2.7.
