Hi I have some problem with generating docs, (Warning, treated as error: failed to reach any of the inventories with the following issues: intersphinx inventory 'http://docs.python-requests.org/en/master/objects.inv' not fetchable due to <class 'requests.exceptions.SSLError'>: HTTPSConnectionPool(host='2.python-requests.org', port=443): Max retries exceeded with url: //en/master/objects.inv (Caused by SSLError(SSLError(1, '[SSL: TLSV1_ALERT_INTERNAL_ERROR] tlsv1 alert internal error (_ssl.c:877)'),))) Can you help me please?

@patricia1387 Apologies for the delay on reviewing this; I'm on vacation and won't be able to give it a thorough review and merge until next week when I'm back.

The issue with Requests has been happening from time to time. Don't worry about it; as long as any changes to the docs look right to you from the source, and the other builds pass, I'll deal with the docs issues myself before or after merging.

Thank you so much for the contribution!

@patricia1387 So... it turns out that my company is migrating off of Jive effective this month. Once that happens, I'll have no way to test or maintain this package. I'll merge this PR now as it looks good to me, but I'm going to be considering this package abandoned within the next few weeks and will be looking for a new maintainer.
