selectively changing d3 elements when Backbone model changes

	# note that this function is called whenever a GeoPoint model changes
	# Backbone will pass in geo_point, which refers to the changed model
	# @geo_points refers to the entire collection of GeoPoint models

	# update the bound data
	geo_points = @geo_points.reject (gp) => gp.get('markedForDelete')

	geoPointMarkers = d3.select('#geo-point-layer').selectAll("g")
	.data geo_points, (d) =>
	d.cid
