So that's what I've been working on the last few days, as well as [documentation](https://github.com/vertica/ddR/wiki/Drivers-and-Backends).\r\n\r\nMy goal with this first pass is to not change anything too drastically, just tighten up what's already there. The biggest change is in the initialization for the parallel driver, and relying a bit more on the parallel library.\r\n\r\nRight now one test is failing, but I'll likely have that fixed tomorrow and
