Trying to highlight adjacent tracts that are in the same block, but the overridestyle isn't working.  Also made a more limited census set so it can be loaded faster.
Now am highlighting the rest of the blocks in the same tract as the one clicked on in red.  Also saw that the placement of revertStyle after override was cancelling out the red highlighting, now fixed.
Zoom dependent strokeweight, not sure if working.  TBD make python notbook to generate tract shapefile/geojsons, want outlines and population and acreage.  Also a ctrl click to select adjacent properties, how to detect ctrl key?
See what happens with a geojson converted from a shapefile that had a grs80 us-feet projection- does the github or google maps viewer view it correctly or are the units misbelieved to be lat/long?
Converted the projection of the shapefile to EPSG:4326, now showing up fine in google maps.
Forgot to add js file.
Make color scale reflect range of parcels
Experimenting with placing infowindow away from click so that it doesn't obscure map right where interest is.   Probably need to get into custom info windows ahown in the http://gmaps-samples-v3.googlecode.com/svn/trunk/smartinfowindow/js/smartinfowindow.js and similar.
Trying to make info window appear off to the side, but it moves when the map is dragged- it is probably the wrong tool, how to make a fixed text box?
Getting rid of infowindow, now instead have info panel on side.  Next work on multiple selections, also have clear buttons on info panel.
Making a button that will allow multiple blocks to be selected.
Meant to calculate totals for multiple blocks selections, but this is selecting multiple tracts and showing the stats for the aggregate tracts.  Also clear selection doesn't work.
Fixed some errors with button names, next fix block selections.
something is wrong with tract highlighting, looking for dupes in selected blocks doesn't work yet.
Multiple selection is sort of working, but clicking on already clicked on blocks makes them not get highlighted.
Now can select multiple blocks fine without previous glitch, need to restore tract visual
Now tract visual is showing up correctly again.  Next to corner points to define a box selection.
