A lot of firsts on this for me, including the first time I've really used github other than just git clone.

I wrote this because I tend to write and rewrite queries a lot, and a lot of times ORMs get in the way.

Admittedly, I have different use cases, as I work in tables with 10 billion rows and, more frequently, tables with 100m rows, so sometimes I have to wrestle out all sorts of performance. In addition to that, I needed to come up with a good way of merging data from geographically and system-diverse databases at runtime for what is effectively a dynamic metadata file system (large physics sets). This isn't always easy to do, although I'm looking into possibly using Presto instead of something like this.
