Update 2017-12-23

Update 2017-12-23: This isn't quite right. The 0 and 24 columns should be added together, because they're capturing a distinction that isn't important (the idea of "service days"). I think I'm also missing data for the MBTA Green Line for the 1am hour, since that's 25:xx and while I don't have my script anymore I suspect it jkust iterated up to 24.
