Rudimentary rethinkdb python library with some smarts (and maybe some dumbs)
## What? Why?
As of now there is a very small amount of code here. I had three projects using the Rethinker class, and had enough code churn inside the class that it became too painful to keep the three copies in sync. Thus, a library shared among them.
Three main purposes:
- round-robin connections among database servers
- make sure connections close at proper time
- retry retry-able queries on failure
Not really a connection pool, because it doesn't keep any connections open, but it does take care of connection management.
