added grid as well, with styles
added server bit to generate hpms totals per grid
modify .gitignore
stroke for hpms; allow zoom out

for attempt to color the map grid squares
color by numbers

grid cells colored by sum_vmt, 2009

linear leaves too much as shades of white, and square (power
of 2) goes the wrong way, so I chose 1/2 power (sqrt)
put the non-totals rows back in

prepping for generating grid by grid data for web UI
get rid of non-totals version of grid data

only using 2009 to color grid squares
