[PyFeyn] problems with installation

[Andy Buckley]

Hi Vroni,

We've not updated pyfeyn for quite some time... and Python itself has
evolved in-between, meaning that some of the dependencies that we have
declared are now out of date.

I will try to find time to do some updates soon -- in particular I'm
surprised that that SyntaxError is still occurring: I thought we had
eliminated use of "as" as a variable name > 1 year ago! (It used to be
valid syntax but became illegal with Python 2.6 or so, when "as" became
a Python langauge keyword.)

Glad that you are finding PyFeyn useful! I'll let you know when I've
done the necessary updates.

Andy
