[Pyparsing] cPyparsing Is a Faster PyParsing

[Evan H. <eva...@gm...>]

I rewrote PyParsing in Cython as part of my efforts to speed up Coconut
<http://coconut-lang.org/> and Undebt <https://github.com/Yelp/undebt>. You
can check it out on GitHub here <https://github.com/evhub/cpyparsing>, or
download it from PyPI with `pip install cpyparsing`. In my testing with
Coconut, I've found it to be about 30% faster, so if you're looking for
maximum PyParsing performance, you might want to check it out.

Right now, it uses very few Cython features, so there's still a lot of room
for improvement. If anyone wants to try strategically moving functions over
to use `cdef` or `cpdef` and submit a PR, that would be much appreciated!

Cheers,
Evan Hubinger
