MAKE FASTER!

Parallize checking for paths-in-squares. Cheap way to increase speed for
code that otherwise needs heavy optimization.

Not as fast as I'd like… ~1m faster on my Core i5
1st revision of working choropleth generation

Use pandas and folium to create a choropleth of "bikeable" square miles
of Albuquerque.

Only display those square miles that have paths (i.e. a bikeability
score) to reduce clutter.

Commit example output (ABQsquares.json, data.json, map.html).
