Update docs

[gbrener]

Since forking from IOPro the documentation has not been updated. Many documents still mention IOPro or details that no longer relate to Mongo.

I would be glad to help out if this project is expected to move forward. Is there something out there that has superseded the need for this package? I need to load large data sets into Pandas using authenticated connections

We plan to keep moving this project forward, unless something better exists out there. Contributions are welcome!
