Track historical data #4

The updates.json file is now recording all of the scrapes.

Let's compare the most recent scrape to the previous one and put a little green/red arrow next to the rankings to show up or down movement.
Track in-season progress with a line chart on the page.

Reminder: There's been a little progress on this already. "div.chart" is already on page. dot-plot.html has the beginnings of the charts, too.

Is the cleanest way to do the up/down arrows to look back at the rankings before the most recent game? Then they'd be relevant for a few days, rather than just "yesterday's rankings".

So you'd have to:

look at one of the sites to find the most recent completed game
search the previous rankings for one that matches the day before that game
math the differences between each ranking ... if it was calculated that time
store the values in an array
draw the arrow and "+/-5" based on the result if it's in the array

A simpler way to do it would be to say "last 7 days" or "last 4 days" or some approximation of "most recent game" without having to actually find that game. "T-4 days" would be a lot easier to compile.
