Enhc svg map

SVG map solution.

Uses an SVG map and JS to zoom in on the selected country and
highlight its fill color. Solution can scale to any country in the
known world.

Known problems:
- The gzipped, minified svg map size is still a little too large at
367kb. We could investigate a smaller map or tweak this solution to use
svg maps that are separated by regions or countries.

TODO:
- Add build process to minify svg files.
- Separate JS into separate files.

This mapping is pretty onerous. @annalee or @khandelwal Do you remember if there's a specific reason for a three-letter code? The only thing I can think of is the potential to map to fund codes?

We could either switch to use two-character identifiers, or modify the SVG file to use the three-character codes.
