Add export of centroid position and number of schools in neighborhood
Add Count annotate function
Add override of bootstrap css margin
Remove specific stylings for different accordions

Not sure why this was here, but was causing some weird
behavior in the list views
Add function to pan and display popup to neighborhood

This set of changes does a few things:
- adds a neighborhoodPan function that has most of the
logic for panning/zooming to a neighborhood given
a name, number of schools, and a lat+lng
- adds a thin wrapper to make this somewhat portable
to both the accordion group and the geojson import
for leaflet
Add some data to html to be used by pan function
Add closing div for accordion
Use separate popup layer to store popups

Makes it easier to remove them when changing from neighborhood
to list view
