What I did for the hackathon

1.  Instead of saying {size: "small"} I have it you enter the number {size: 314}.  You can get any width :-)

2.  Choosing individual tiles (to color, for example) is difficult right now.  Sorting the geojson tiles by name, I can use $("path").eq(1) to get Adjuntas, 2 for Aguadilla, etc.
