Hello Drill devs, A few months ago I submitted this patch for package level documentation in Drill. I received some comments and fixed a few reported issues with the patch, but I did not follow through to try to get a +1 from another committer. With everything that was going on stabilizing Drill for 1.0, it just fell by the wayside.
Would someone be willing to take a pass over these docs so I can get them merged? The actual changes aren't too large, the diff looks big mostly because I have the apache license header on a bunch of small files. https://reviews.apache.org/r/29278 https://issues.apache.org/jira/browse/DRILL-1904
