last thing...
Implemented zip code polygons on Google map

1) Created an invisible textarea element in our index.html. I iterated
through each of the 20 zip codes, formatted all of the path entries in
json, and inserted them into the textarea all as one array of json
objects
2) Modified main.js to fill polygons (as opposed to creating circles)
3) Created 5 levels of intensities and got the colors from
colorbrewer2.org. Applied these intensities to the files, depending on
the graduation levels that I had created.
4) Cleaned out all the code pertinent to map circles.
