Notice: ARIMA Sector Report Revisions

Just a minor note for the observant---I'm reprinting and reposting the ARIMA sector reports since March 12.  I was using ggplot2 as my graphics package (in R), which changed the way it formatted dates in a recent upgrade.  Since March, this meant the ARIMA forecast plots had the date format "2012-03-12" rather than simply listing full months by name, such as "March."  Past data was rerun, so everything else is identical, but the format of the date axis has been updated to the original, monthly format for purely aesthetic reasons.
