I got comments: Very nice work. I am going to read this a couple times and learn all I can from it. I have been trying to reduce the memory footprint on this guy (https://github.com/leaderanalytics/LeaderPivot https://github.com/leaderanalytics/LeaderPivot) for a couple weeks and have not moved the needle one bit (literally). If you could give me shove in the right direction I would appreciate it greatly.
