[PyFeyn] problems with installation

[Andy Buckley]

Hi again,

In fact, I just noticed that you are using PyFeyn 0.3.1. We released
0.3.2 in 2009! The reason for this is that PyPI wasn't updated when
0.3.2 was released... but I've done that now.

I'm pretty sure that the 0.3.2 release fixed the "as" problem. Not sure
about the setuptools one, but I just made some changes to solve that,
too, and will make a new 0.3.3 release (if Georg agrees). He has done a
lot more development than I have since the last public version, and it
would be nice to get those new features into an official tarball / PyPI
release. Is that ok, Georg?

Cheers,
Andy
