inspire-schemas is not installable in a pristine environment

[jacquerie]

Because of the six import in setup.py one needs to have it installed before installing inspire-schemas. See: https://github.com/inspirehep/inspire-next/pull/2449#issuecomment-309303373

I'm currently working around this by pushing wheels, but I hope there is a better solution...

six is only used in setup.py to provide the next() function, but the next() global seems to exist both in python 2 and python 3 with the same semantics, so I don't know if it is really useful for anything there.

The six.next is for python<2.6 (that we don't support), so not needed.

btw. this works for me without any changes...

Note that you're installing my wheel, and not from sources! Here's what I see with inspire-schemas==37.0.0, for which I made no wheel:

Ohh... so that's what you meant, that you actually released a wheel packaged version on pypi. okok
