Description : High-performance 2D spatial index for rectangles
of points and rectangles by Vladimir Agafonkin, based on an optimized
R-tree data structure with bulk insertion support.
Spatial index is a special data structure for points and rectangles that
allows you to perform queries like "all items within this bounding box"
very efficiently (e.g. hundreds of times faster than looping over all
items). It's most commonly used in maps and data visualizations.
node-rbush is required for OpenLayers 3 (#774561).
