In the middle of converting graphs to ggplot2 commands.  Had to make changes to the criteria (In "TESTING!!") to make the labels, although I might not need that with my latest attempt. Committing now to save progress, because I'm losing track of what I've done, and that's what this thing's for, yes?
Changed x-axis labels and tick marks.  Going to change the order of if/else statements around benchmark lines and titles
At a good commit point.  ggplot (single and multiplot) graphs with titles, legends and benchmark lines working.
