Update or delete pip package

[mmdriley]

The project README suggests using the google-apis-client-generator package. That package was last updated more than two years ago (August 2013) and is missing a lot of commits. We should update the package to a latest version or delete it.

I updated the README to point to a specific, tested version of that package.

Whoops. Wrong repo.

I have released version 1.4.3 today. https://pypi.python.org/pypi/google-apis-client-generator/1.4.3

@SurferJeffAtGoogle I believe we can close this. (I don't have write access)
