Hello all, I began working on some documentation for the packages in Drill. I have posted a patch with my initial work on Drill-1904. I have also uploaded a patch to reviewboard, please add your comments there about how the documentation can be improved. I am working on filling out the package level docs for the rest of the project, if you'd like to pick up a few packages feel free to respond to this thread to claim them (notice I have left few TODOs in packages I do not know well).
