Track progress over time, do projections

@rbparson assigning this to you for now, if you want to task someone with it ( @unusualbob perhaps? ). It should be a fairly straightforward task (use a setInterval to push this data into redis or mongodb, then render the past n calculations on pageload. involves (ideally) modularizing the existing progress calculations.) I can assist with predictions once the graphing task is complete.

This would be a huge boon to @RobertRice919's needs.
