Adds two simplifying assumptions to how we process analytics stats: * Sets the atomic unit of work to: a stat processed at an hour boundary. * For any given stat, only allows these atomic units of work to be processed in chronological order. Adds a table FillState that, for each stat, keeps track of the last unit of work that was processed.
