Doesn't install properly from PyPI

[call]

Attempting to install from PyPI produces the following errors:

$ pip3 install bigquery-schema-generator
Collecting bigquery-schema-generator
  Downloading bigquery-schema-generator-0.1.2.tar.gz
    Complete output from command python setup.py egg_info:

        import pypandoc

After installing pypandoc and trying again, I encountered this error:

pip3 install bigquery-schema-generator

I was able to work around this by cloning this repo, cd'ing into the local repo and installing via pip3 install ., but it'd be great if this installed properly from PyPI.

Also, this is a much-needed utility. I'd previously been semi-solving this problem using wolverdude/genSON to infer a JSON schema, then converting that to BigQuery schema with some custom code, but this looks much more idiomatic. Looking forward to taking it for a spin. Thanks, and keep up the good work.

(Sorry for the delayed response, I'm seeing this just now. I thought GitHub would email me, but it didn't.)

Thanks for reporting the installation problems. This is my first submission to PyPI, so clearly I missed something. I'll try to fix this soon. Glad that you found this useful.

Took me a couple of tries, but I think I fixed the problem with v0.1.4 which I pushed to PyPI. This new setup.py no longer requires 'pypandoc' to be installed for the end user.

Tested on another Ubuntu machine:

$ sudo -H pip3 install bigquery-schema-generator
[sudo] password for brian:

I've verified that the latest version on PyPI (v0.1.5) installs properly on MacOS 10.13.2 as well. I'm going to mark this as Fixed, but please reopen if there's a problem.
