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?
