Moved Stats-related methods into a Util.  v1.0.0 Yay!  Time to start writing some decent docs!
Forgot to iterate version on package.json!
All unit tests now passing.
Added some info-level logging to the stat processor. Also, added ability to specify the grain at which one wishes to process the stats. The default is hourly, but I'd like to also be able to process by day, month or year.
